We’ll start with routine 5,000-mile services and work up to major 100,000-mile milestones, highlighting what needs to be checked or replaced at each stage.

Whether you drive a rugged GMC Sierra or a family Chevy Equinox, these maintenance guidelines will keep your vehicle safe, reliable, and performing its best. Read on for a detailed schedule of Chevrolet & GMC maintenance tasks – plus expert insights, a handy checklist of services by mileage, and answers to common questions – all to ensure you can keep your car running strong in Corsicana’s conditions year-round.

 

How often should you service your Chevrolet or GMC vehicle?

You should service your Chevrolet or GMC at regular mileage or time intervals to keep it in peak condition. In general, plan on an oil change and tire rotation about every 5,000 to 7,500 miles, or roughly twice a year. This routine service includes a multipoint inspection of your fluids, brakes, and other components. On top of that, major maintenance items come due at 15,000-mile increments (15k, 30k, 45k, etc.), when filters and fluids get replaced and key systems are inspected more thoroughly. Following this mileage-based car care schedule ensures all parts of your vehicle are maintained on time, helping to prevent breakdowns and keep your Chevy or GMC running reliably for many years. (Always check your owner’s manual for model-specific intervals.)

Now, let’s break down the recommended maintenance tasks at various mileage milestones. If your vehicle is coming up on any of the intervals below, you can always schedule a service appointment with our Corsicana service center for expert care.

  • 100,000 miles: Replace spark plugs (iridium plugs typically last ~100k); inspect/replace ignition wires or coils as needed; inspect catalytic converter/O2 sensors; ensure all fluids (coolant, trans, diff) have been changed; continue 5k/15k service cycle.
     

(Note: “Repeat 5k/15k services” means continue the basic oil change, tire rotation, inspections, and earlier interval items on the same cycle. Always adjust for your specific model’s requirements and driving conditions.)

 

 

5,000 Miles – Routine Maintenance

At every 5,000 miles (approximately every 6 months), your Chevrolet or GMC will need its most frequent basic service. This routine maintenance keeps your engine lubricated and your tires wearing evenly, forming the foundation for your car’s longevity. Here’s what to do at the 5,000-mile mark (and at roughly every 5k thereafter):

  • Change Engine Oil and Filter – Replace the engine oil with the recommended grade and install a new oil filter. Regular oil changes remove contaminants and keep your engine running smoothly. Many modern GM vehicles have an Oil Life Monitoring system that often allows longer intervals, but 5,000 miles is a safe rule of thumb for frequent service, especially under severe driving conditions. In fact, advances in oil technology and GM’s Oil Life System have made the old 3,000-mile oil change largely obsolete.
     

  • Tire Rotation and Air Pressure Check – Rotate your tires to even out tread wear, and adjust tire pressures to the recommended PSI. GM generally recommends rotating tires about every 7,500 miles, but doing it with each oil change (5k miles) is an easy way to remember and can extend tire life. Properly inflated, rotated tires promote better handling, fuel economy, and tread longevity.
     

  • Inspect Fluids – Check all vital fluids under the hood. This includes engine coolant level, brake fluid, power steering fluid (for models that have it), transmission fluid (if accessible), and windshield washer fluid. Top off any that are low, and note if any fluids seem to be consuming or leaking abnormally (which might indicate an issue).
     

  • Brake Inspection – Have the brake pads and rotors visually inspected at every oil change interval. At 5,000 miles, brakes on a new vehicle should be in good shape, but regular checks ensure any wear or issues (like uneven wear or low brake fluid) are caught early. The technician will measure pad thickness and can alert you if they’re wearing faster than expected.
     

  • General Multi-Point Inspection – It’s wise to perform a quick all-around inspection at these service visits. Our Certified technicians will typically do a Multi-Point Vehicle Inspection, checking things like lights, wiper blades, battery health, drive belts, hoses, and looking for any leaks or irregularities. This ensures any emerging problems are identified. (Even minor items like a burnt-out bulb or a dirty air filter can be addressed during your visit to keep everything in top condition.)
     

Expert Technician Tip: Don’t forget to check your oil level between changes. It’s normal for engines to use a little oil over time. We recommend checking the dipstick once a month. Keeping your oil topped up (between the “min” and “max” marks) ensures your engine always has adequate lubrication. If you notice a significant drop in oil level between 5,000-mile changes, let us know – that could point to a leak or oil consumption issue that needs attention.

During each 5,000-mile service, you’ll also want to listen for any new noises or feel for changes in how your vehicle drives. Little signs like a slight vibration, pull in the steering, or longer braking distances can be symptoms that something needs maintenance. By getting the oil change and tire rotation done on schedule and having our service team perform a quick checkup, you set a solid baseline for vehicle health.

15,000 Miles – Minor Service

By the time your Chevy or GMC reaches about 15,000 miles (roughly 1 to 1.5 years on the road for many drivers), a few additional maintenance items come due. The 15k service builds on the 5k routine with some extra focus on filters and an overall check of wear-and-tear items. Here’s what to include at 15,000 miles (in addition to all the 5,000-mile tasks like oil change, tire rotation, etc.):

  • Cabin Air Filter Replacement – At 15,000 miles, it’s generally time to replace the cabin air filter. This filter cleans the air that comes through your HVAC system (for heating/air conditioning). Over a year or so, it fills up with dust, pollen, and debris. Replacing it will keep your interior air fresh and ensure your A/C and heater work efficiently. (If you drive on dirt roads or in heavy pollen areas around Corsicana, you might even do this more often.)
     

  • Engine Air Filter Inspection/Replacement – The engine air filter should be checked around this interval. Many manufacturers recommend replacing the engine air filter somewhere between 15k and 30k miles under normal conditions. If your filter looks dirty at 15k, go ahead and replace it to help your engine “breathe” well. For vehicles in especially dusty environments, changing the engine air filter closer to 15,000 miles is advisable. Otherwise, it may be safe to wait until the 30k service for a fresh filter – but at least inspect it now.
     

  • Brake System Check – While you’ve been inspecting brakes at each oil change, 15,000 miles is a good milestone for a thorough brake system evaluation. This includes measuring brake pad thickness, inspecting brake rotors for any grooves or warping, and checking brake lines and hoses. It’s also a smart time to check the brake fluid level and condition. Brake fluid that’s dark or contaminated with moisture may need to be flushed in the near future (more on this at the 30k/45k marks). Ensuring your brake pads still have plenty of life (many new pads start around 10-12 mm; replacements are needed when they wear down to ~3 mm) will keep your stopping power strong.
     

  • Battery Test – At around 15k miles (likely 1-2 years old), your battery is still relatively new. However, it’s wise to test the battery’s health, especially before extremes of summer heat or winter cold. Our service department can perform a quick battery load test to make sure it’s charging properly and holding sufficient voltage. If the test shows any weakness, we might keep an eye on it or re-test at the next interval. (Car batteries typically last 3-5 years, but hot Texas weather can shorten their lifespan to the lower end of that range.)
     

  • Rotate Tires & Inspect Tread – Yes, you should rotate tires at 15k as part of the repeating 5k service, but also take a close look at the tire tread depth now. By 15,000 miles, your original tires will have some wear. Use a tread depth gauge or the penny test (insert a penny into the tread with Lincoln’s head down – if you see the top of his head, the tread is too low). Ideally, you’ll have much more tread left at 15k (new tires often have ~10/32” of tread; at 15k you might be around 7-8/32” if wearing evenly). If you notice any uneven wear (edges balding, center wear, etc.), this could indicate the need for a wheel alignment or adjustment of tire pressures.
     

Technician Tip: Living in Texas, you know how dusty our air can get. If you frequently drive on rural dirt roads or during dusty conditions, don’t wait too long on your engine air filter. We’ve seen filters clog up faster than expected in dusty environments. It can be a good idea to change the engine air filter closer to 15,000 miles instead of 30,000 in such cases. A clean air filter helps your engine run efficiently and can even improve fuel economy, so it’s a cheap fix that goes a long way.

The 15,000-mile service is often considered a “minor” service interval, but it plays a major role in preventative maintenance. Refreshing the air filters keeps both you and your engine breathing cleanly. A detailed brake check gives peace of mind that you can stop effectively. And addressing any uneven tire wear or battery weakness now will save you trouble later. After this service, your vehicle will have fresh filters, well-lubricated moving parts, and should be in top shape as you head toward the 30k mark.

30,000 Miles – Major Service

Hitting 30,000 miles is a significant milestone for vehicle maintenance. Around 30k (approximately 2 to 3 years of driving for many owners), several important components need attention beyond the regular oil changes and inspections. This is often considered a “major service” interval. By taking care of these items at 30k, you’ll help avoid performance issues and breakdowns as the vehicle ages. Here’s what the 30,000-mile service generally includes:

  • Engine Air Filter Replacement – If you didn’t replace the engine air filter at 15k, now is the time. By 30k miles, the air filter has definitely earned a change. A clogged air filter can reduce engine performance and fuel economy. Swapping in a new one will ensure your engine gets plenty of clean air for combustion. (As noted earlier, dusty driving conditions warrant earlier changes, but 30k is the outer limit for most filters.)
     

  • Fuel Filter Replacement (if applicable) – Many modern GM vehicles have “lifetime” fuel filters integrated with the fuel pump (especially gasoline engines), so they might not require a fuel filter change at 30k. However, if your vehicle does have a serviceable fuel filter (for example, some older models or certain trucks, and especially diesel engines), manufacturers often recommend replacing it around the 30,000-mile mark. A clogged fuel filter can cause rough running or power loss, so if your model has one, it’s wise to put in a new filter now. (Check your owner’s manual or ask our service advisors if you’re unsure whether your fuel filter needs regular replacement.)
     

  • Brake Fluid Flush – By 30,000 miles (or roughly 3 years), it’s highly recommended to flush the brake fluid if it hasn’t been done yet. Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. That contamination can lower the fluid’s boiling point, leading to diminished braking performance (a spongy pedal feel) and potential internal corrosion in brake lines/calipers. Many manufacturers suggest replacing brake fluid somewhere between about 20,000 to 45,000 miles. Performing a brake fluid exchange at ~30k miles will refresh the system with clean fluid. This service involves fully bleeding the old fluid out of all brake lines and refilling with new DOT3/DOT4 fluid as specified. The result is firmer brake pedal feel and protection of your brake components.
     

  • Battery Replacement (if Needed) – At 30k, you’re likely around the 3-year mark on the factory car battery. In Corsicana’s hot climate, three years can be a typical lifespan for a battery. During the 30k service, we’ll test the battery’s health again. If there are any signs of weakness (e.g. it’s testing low, or you’ve noticed slow cranking on startup), it may be prudent to replace the battery now. Proactively installing a fresh battery around the 3-4 year point can save you from an unexpected dead battery later. (If the battery still tests strong, you can probably continue using it, but keep in mind the Texas heat continually takes a toll. We’ll likely test it at each service going forward.)
     

  • Inspect Belts and Hoses – Rubber components like the serpentine belt (which drives accessories like the alternator, power steering pump, A/C compressor) and various coolant/heater hoses should be thoroughly inspected at 30k. Look for any cracks, fraying, glazing, or bulges. The serpentine belt on many GM engines can often last beyond 50-60k, but it’s not unheard of for a belt to show wear by 30k, especially if the vehicle has been in harsh conditions. Hoses can likewise degrade from heat over time. If any belt or hose looks compromised, replacing it now is cheap insurance against a breakdown later (a broken belt can leave you stranded, and a burst coolant hose can cause an overheating episode). Often, everything will still look fine at 30k, but it’s a checkpoint to begin monitoring these items closely.
     

  • Alignment and Suspension – It’s a good idea to have your wheel alignment checked around this time, especially if you’ve noticed any pull in the steering or uneven tire wear by 30k. Corsicana’s roads, occasional potholes, or curb bumps can knock alignment out over a few years. Correct alignment will prevent premature tire wear and ensure straight, efficient tracking. Additionally, a quick inspection of suspension components (shocks/struts, bushings, tie rods, etc.) at 30k is wise. Most of these parts should still be in good shape at this mileage, but if you’ve been driving on particularly rough roads, you might catch an issue early. For example, a leaking shock absorber could be identified and replaced to maintain proper ride and handling.
     

Service Insight: Not all spark plugs are created equal. By 30,000 miles, you typically don’t need to replace spark plugs in modern Chevrolets and GMCs – unless your engine uses older-style copper spark plugs. Most newer GM vehicles come with long-life platinum or iridium spark plugs that can last up to 100,000 miles. However, if you drive an older model or a performance vehicle that happened to use copper plugs, those would need changing roughly around 30k. Our technicians keep track of what your vehicle requires. Generally, for 2010s and newer Chevy/GMC models, spark plug service isn’t on the menu yet at 30k. We’ll plan for that closer to the 90k-100k mark.

By performing the above services, the 30,000-mile maintenance visit gives your vehicle a fresh start on many wear items. You’ll leave with new filters (oil, air, etc.), possibly new brake fluid and other fluids refreshed, and confidence that belts, hoses, and other components have been inspected or renewed as needed. This major service lays the groundwork for a trouble-free ownership experience as you head into higher mileage. It’s also a great time to address any lingering concerns – maybe you’ve noticed a slight squeak or a drop in fuel economy; let us know, and we can investigate during this thorough service.

45,000 Miles – Maintenance Checkpoint

At 45,000 miles (around 3 to 4 years old), your Chevrolet or GMC will undergo another important maintenance checkpoint. Think of the 45k service as an expanded follow-up to the 30k major service. Many of the 15k tasks repeat here, and some items that were inspected at 30k may now need actual replacement, given additional wear. Key focus areas at 45,000 miles include your braking system, tires, and any components that may have been borderline at the last service. Here’s what to address at 45k (along with the routine oil change, tire rotation, etc.):

  • Replace Brake Pads (If Worn) – By ~45,000 miles, many vehicles will need their first brake pad replacement (front pads in particular, since they usually wear faster). During the 45k service, the technician will measure the brake pad thickness. If the pads are at or below the minimum safe thickness (around 3 mm remaining), we’ll replace them to restore full braking performance. Even if they’re not fully worn out, some drivers choose to replace pads proactively around this mileage to maintain strong braking response. Along with new pads, the brake rotors will be inspected and either resurfaced or replaced if needed (rotors that are deeply grooved or below thickness spec should be replaced for optimal braking). Ensuring fresh brake pads at this stage keeps you safe on the road and prevents metal-on-metal damage that happens if pads wear out completely.
     

  • Brake Fluid Change (if not done yet) – If the brake fluid wasn’t flushed at 30k, it should be done by 45k miles for sure. As mentioned earlier, brake fluid degrades with time and use. Changing it by this point follows the common 2-3 year recommendation to maintain high boiling point and corrosion protection. So at 45k, we’ll likely perform a brake fluid flush (unless we already did it at 30k) to keep the brake system in top shape. Combined with possibly new brake pads, this will make your brakes feel almost brand new.
     

  • Tire Inspection & Replacement – Tires often reach the end of their useful tread life somewhere between 40,000-50,000 miles (though it varies with tire model and driving style). At 45k, a careful tire inspection is in order. Measure the tread depth on all tires and look for signs of dry rot or sidewall cracks (especially in Texas heat, rubber can start to dry out over years). If your tire tread is getting low (for instance, 4/32” or less remaining), you should plan for new tires soon. Many drivers will be replacing their original tires around this interval. Having adequate tread (and a fresh set of tires when needed) is critical for traction and safety, particularly in wet weather. If you do get new tires now, be sure to have them balanced and the vehicle aligned to protect your investment.
     

  • Alignment & Suspension Check – Even if you haven’t noticed issues, it’s smart to perform another alignment check at 45k, especially if you’re installing new tires. This ensures the wheels are properly aligned (camber, toe, etc.) so the new tires wear evenly. At the same time, we’ll examine the suspension components again. Shocks and struts by 45k may show the first signs of wear – perhaps a slight leak or reduced damping. If you’ve felt the ride getting harsher or more bouncy, that points to shock/strut wear. While many shocks last past 50k, some may be recommended for replacement around this time to maintain optimal ride and handling. Likewise, any bushings or chassis components that are showing play (like ball joints or tie rod ends) should be addressed to keep the vehicle tight and responsive.
     

  • Engine & Drivetrain Fluids – At 45k, take stock of the other fluids that haven’t been changed yet. Engine oil is being changed regularly (every 5k), and we likely changed brake fluid and maybe coolant or others by now. If coolant was not changed at 30k (some owners wait until ~5 years or ~50k+ miles), we will check its condition now and likely plan to replace it by the next interval (60k) at the latest. Similarly, automatic transmission fluid might be due soon if not already done – some transmission services are recommended at 45k in severe use cases, though many GM transmissions can go to 60k or beyond before a fluid change. Use the 45k service as a time to plan the upcoming fluid changes: for example, if you tow or haul heavy loads with your truck, we might choose to service the transmission around this mileage to be safe. If not, we’ll target it at 60k. The key is to ensure no fluid is forgotten indefinitely.
     

Technician Tip: By 40k-50k miles, tires are often nearing their end. A quick trick to check tread: use a quarter instead of a penny. If part of Washington’s head is always covered by tread, you have more than 4/32” remaining. If the top of his head is visible, your tread is about 4/32” – time to start shopping for tires. For safety, don’t let your tread go below 2/32” (the wear bars on the tire will be flush with the tread at that point). Remember, new tires significantly improve braking and wet-road traction. We can help you find the right set when the time comes.

The 45,000-mile maintenance visit essentially repeats much of the 15k service but with greater emphasis on wear-and-tear replacement. By this point, brake components and tires demand close attention. Addressing them now (new brake pads, fresh fluid, possibly new tires) resets those systems so your vehicle feels and drives like it did when newer. After 45k service, you should have confident braking, good tire traction, and a vehicle that’s well-prepared to take on the second half of its first 100k miles.

60,000 Miles – Mid-Life Service

Reaching 60,000 miles is a milestone that signals your Chevrolet or GMC is about halfway (or more) through its first century of miles. The 60k service is another major service interval, similar in importance to the 30k service, but now with the vehicle having seen more wear. At 60,000 miles (roughly 5 years old for many drivers), several fluid replacements are typically due, and a few significant components may require renewal. Performing these services will help avoid problems as the vehicle ages into higher mileage. Here’s what to cover at 60,000 miles:

  • Coolant Flush (Antifreeze Replacement) – Most coolant (antifreeze) formulations, including GM’s long-life DEX-COOL®, are rated for about 5 years or a certain mileage. While some owner’s manuals might cite up to 100,000+ miles or 5 years for coolant, it’s generally a good idea to flush the engine coolant around 60,000 miles to be on the safe side. Fresh coolant will ensure your engine continues to run at the proper temperature and protect against corrosion in the radiator and engine block. During a coolant flush, we’ll drain the old coolant, flush out any residue, and refill with the correct blend of new antifreeze and water. This service is especially important in hot climates like Texas, where coolant degrades faster. Proper cooling system maintenance at 60k prevents overheating issues down the road.
     

  • Automatic Transmission Service – By 60k, it’s wise to service the transmission fluid on automatic transmissions (manual transmissions and differentials may have their own intervals, but those are often longer; we’ll check those too). Transmission fluid breaks down from heat and use over time. Replacing the ATF (and filter, if applicable) around 60,000 miles helps maintain smooth shifting and prolongs transmission life. This is particularly crucial if you do a lot of stop-and-go driving, towing, or drive in hilly terrain – all of which put extra stress on the transmission. Some newer GM models have transmissions labeled “filled for life” or very long intervals, but in practice, changing fluid at 60-70k can be very beneficial for long-term reliability. We’ll use the specified GM transmission fluid for your vehicle and perform either a fluid drain-and-fill or a full flush, depending on the model’s service procedure.
     

  • Spark Plugs (for Certain Engines) – For most modern GM engines with iridium spark plugs, 60k is still shy of the replacement point (which is often 90k-100k). However, there are a few cases where spark plugs might be due around 60k: for example, if your particular model or year calls for 60k plug changes (some older designs or high-performance engines might), or if you notice any symptoms of worn plugs (like rough idle or decreased fuel efficiency). Generally, if your vehicle is running fine, we will likely leave the spark plugs until the 90k service. But we will inspect a sample plug or two at 60k to gauge their condition. If by chance your vehicle uses platinum plugs with a 60k interval, we’ll change them now. Always refer to the manufacturer’s spec – many Chevrolet/GMC vehicles explicitly list 97,500 miles or even 120k for plug replacement. So, think of spark plugs as “on deck” at 60k, to be safe by 100k.
     

  • Serpentine Belt – The accessory drive serpentine belt should be carefully inspected at 60k and likely replaced if any signs of wear are present. By this mileage, the belt has done a lot of work. Even if it hasn’t broken or started squealing, the rubber may be aging. We check for cracks in the ribbed side, fraying on the edges, or any stretching. Replacing the serpentine belt around 60,000 miles (or at least by the time you hit ~5 years) is a cheap insurance policy – a new belt ensures your alternator, power steering, water pump, and A/C keep running without interruption. If the belt still looks good, we might stretch it to the next interval, but be prepared for a new one no later than 90k.
     

  • Battery Replacement – At around 60k, the vehicle’s original battery is very likely near the end of its life if it hasn’t been changed already. As noted earlier, in hot climates a battery may only last ~3 years (perhaps 30-40k miles). If you made it to 5 years/60k on one battery, that’s quite good – but you’re on borrowed time. We strongly recommend installing a new battery by the 60,000-mile mark if it wasn’t done earlier. A fresh battery will provide reliable starts and proper voltage to your electrical systems. This preemptive replacement can save you from the hassle of a no-start situation later on. Our service department offers Battery Service & Replacement with genuine ACDelco batteries, which meet GM’s specifications for your vehicle.
     

  • Differential and Transfer Case Fluids – For trucks or SUVs (Silverado, Sierra, Tahoe, Yukon, etc.) with 4WD or AWD, the differential(s) and possibly a transfer case have their own gear oil that should be changed around 60k (especially if the vehicle tows or sees off-road use). Even on 2WD vehicles, the rear differential fluid can be refreshed at this point. Fresh gear oil protects the gears and bearings in these components. It’s often an overlooked service, but doing it at 60k or so can help these parts last the life of the vehicle. We’ll use the appropriate GM gear oil and additive (if required for limited-slip diffs) when performing this service.
     

  • Comprehensive Inspection – At 60k, we also perform a thorough inspection of the vehicle’s overall condition. We look at the hoses again (any that feel excessively hard or soft, or show surface cracking, might be replaced now to prevent leaks). We’ll check for any oil leaks around the engine, transmission, or driveline, which can begin to develop as gaskets age. We’ll ensure the PCV valve (if serviceable) is clean, and that your emissions components (like the charcoal canister for fuel vapors) are functioning. Additionally, the suspension and steering components get another check – by this mileage, things like shock absorbers could be getting weaker, and bushings might show wear. If you’ve been experiencing any vibration or noises, we’ll diagnose those now. Essentially, the 60k service is a bumper-to-bumper review in addition to the scheduled fluid changes.
     

Expert Tip: Once your car hits about five years or 50-60k miles, keep an eye (and ear) on the cooling system. Hoses and the water pump can start to weaken around this age. It’s far better to replace a marginal radiator hose or a seeping water pump now than to deal with an overheated engine later. During your 60k service, ask us to double-check the cooling system. We’ll make sure hose clamps are tight, the thermostat is working properly, and there are no coolant leaks. A well-maintained cooling system is especially vital in our Texas heat!

After a comprehensive 60,000-mile service, your Chevrolet or GMC will have many of its lifeblood fluids renewed – oil, coolant, transmission fluid, etc. – and critical wear components either inspected or replaced. You’re essentially reconditioning the vehicle at mid-life so that it can continue to perform reliably. Many owners find that after the 60k service, their vehicle drives almost like new again, with smoother shifting, restored cooling performance, and the confidence that major systems have fresh fluids and parts. Now it’s time to aim for that 100k mark with the peace of mind that you’re up to date on maintenance.

75,000 Miles – Preventive Maintenance

The 75,000-mile mark doesn’t usually have a long list of brand-new service items beyond what we’ve already addressed, but it’s an important “preventive maintenance” check as you approach higher mileage. Think of 75k as a reinforcement visit – making sure the maintenance from 60k is holding up, and planning ahead for the big 90k/100k services. Depending on how you drive, some components might start showing age around 75k that earlier inspections didn’t catch. Here’s what to focus on at 75,000 miles:

  • Routine Services – First and foremost, continue the routine 5k and 15k services: change the oil and filter, rotate the tires, do the multipoint inspection, and ensure the air filters (cabin and engine) are clean (replace if needed). By 75k, you may be on your second or third set of filters, and perhaps even a second set of tires if the originals wore out around 50k. Keeping up with these basics is still priority #1.
     

  • Power Steering Fluid Flush – If your vehicle has a conventional hydraulic power steering system (many older models and trucks do; newer vehicles might have electric power steering with no fluid), the power steering fluid could be serviced around 75k. Over time, this fluid can get contaminated and the additives break down. Flushing the power steering fluid at ~75,000 miles can help keep steering components (like the power steering pump and steering rack) in good shape. In fact, many automakers suggest a power steering fluid replacement somewhere in the 75k range. It’s a quick service – we’ll drain the old fluid and refill with fresh fluid of the appropriate type. The result can be smoother, quieter steering operation and prolonged component life.
     

  • Spark Plug Inspection/Replacement – At 75k, we’re getting closer to the typical 100k spark plug replacement for iridium plugs. It’s a good time to inspect the spark plugs if it wasn’t done at 60k. By pulling a couple of plugs, we can “read” their condition – they’ll tell us how the engine is running (proper combustion or any signs of running too hot/cold). If the electrodes are significantly worn or fouled, we may recommend replacing the spark plugs now rather than waiting. While most Chevrolet/GMC models won’t strictly require new plugs until around 90k-100k, some owners opt to change them around 75k as a preventive measure, especially if they notice a slight decrease in performance or fuel economy. New spark plugs can restore peak efficiency and are relatively inexpensive on most engines. If not replaced at 75k, they’ll definitely be on the docket by 90-100k.
     

  • Timing Belt Check (if applicable) – It’s worth emphasizing that many GM engines use timing chains (which are generally “lifetime” but still need occasional check/tension). However, if you own a model with a timing belt (for example, certain GM small engines or older designs – be sure to check your manual), the typical replacement interval for a timing belt is often between 60k and 100k miles. Most timing belts are recommended to be changed by around 90k at the latest, to avoid the risk of the belt breaking (which can cause severe engine damage in interference engines). At 75k, if you have a timing belt, it is definitely time to plan for its replacement soon. We will inspect it (some belts can be visually checked for wear/cracking if they have a cover opening) at this service. If there’s any doubt, we’ll schedule the replacement. (Often, doing it at ~75k can be prudent to not push the limit.) When replacing a timing belt, we also typically change the water pump and belt tensioners at the same time, since those components are in the same area and tend to have similar lifespan.
     

  • Suspension and Ride – By 75k miles, parts of your suspension may start showing their age. If you’ve been noticing a less comfortable ride, more bounce over bumps, or hearing clunks over rough roads, it could be time to replace shocks and struts. Many OEM shocks/struts are well past their prime by 75k. Replacing them will improve ride quality, handling, and even braking (since worn shocks can lengthen stopping distance). We’ll evaluate the suspension during the inspection. Additionally, wheel bearings should be listened to (a growling noise at speed can indicate a bearing starting to fail). And crucially, the brakes that we serviced previously should be checked again – if you got new pads at 45k, by 75k they might be about halfway worn, which is fine, but if you somehow stretched original pads this far, they almost certainly need replacement now. Essentially, nothing in the suspension/braking realm should be ignored at this point – we want a solid chassis as the car heads toward high mileage.
     

  • Climate Control & Other Systems – After many Texas summers, your air conditioning system might be due for a check. At 75k, we can test the A/C performance to ensure the refrigerant charge is still good and there are no slow leaks. Similarly, the heating system and defrosters should be checked as we head into winter. Little things, like the condition of drive belts (reiterating the serpentine belt if not yet replaced), windshield wiper effectiveness, and any burnt-out bulbs or electrical gremlins, should be addressed at this juncture. It’s much nicer to fix these minor annoyances in a scheduled service than to let them pile up.
     

Service Tip: If you’ve noticed your steering has gotten stiff or noisy, you might be low on power steering fluid or the fluid is just worn out. Around 75k miles, a power steering fluid flush can do wonders for steering feel. It’s one of those services people often skip, but our technicians recommend it because it can prolong the life of your power steering pump and rack. Plus, if your car is older and starting to moan or whine when you turn the wheel, fresh fluid often quiets it down.

At 75,000 miles, you’re essentially fortifying your vehicle for the final stretch to 100k and beyond. Addressing the above items ensures that there are no surprises waiting to happen. It’s much easier to schedule a maintenance service now than to deal with an unexpected issue at an inconvenient time. After the 75k service, you can drive with confidence knowing your fluids are fresh, your spark and timing (ignition and engine timing components) are in order, and your suspension and steering are up for the task. Now, the big 90k/100k service horizon is in sight, and your car will be ready for it.

90,000 Miles – Critical Maintenance

90,000 miles is a crucial milestone in vehicle maintenance. By 90k (often around 7-8 years of use), your Chevrolet or GMC has given you lots of service – and now it’s time to give it some major TLC in return. This interval often involves some of the most significant preventative replacements, particularly if your engine has components like a timing belt. Even for chain-driven engines, 90k is when long-life spark plugs typically need changing, and other items that have been in use since day one may finally be due. Here’s what the 90,000-mile service generally entails:

  • Timing Belt Replacement (if equipped) – For any GM vehicle that uses a timing belt (rather than a timing chain), 90,000 miles is typically the absolute latest you’d want to wait to replace it. In fact, many recommend doing it earlier (around 75k) to be safe. A worn timing belt can snap without warning, and on interference engines, that can cause serious engine damage. Replacing the timing belt now is a critical preventive measure. During a timing belt service, we also replace the belt tensioner, and usually the water pump (since it’s accessible while the belt is off, and an old water pump could seize and damage a new belt). Not all Chevrolets/GMCs have timing belts – many have timing chains that usually last the life of the engine with good oil changes – but if your model has a belt (consult your manual or ask us), the 90k service is often centered around this job. It’s a bit of an involved service, but once done, you’re usually set for another ~90k on that new belt.
     

  • Spark Plug Replacement – Nearly all modern Chevrolet and GMC vehicles with iridium or platinum tipped spark plugs call for replacement at this interval (commonly 100k in manuals, but many owners do it around 90k). After tens of thousands of ignition cycles, even long-life plugs begin to wear, increasing the gap and straining ignition coils. We will install a new set of OEM-spec spark plugs to ensure optimal combustion. This will often restore lost power and fuel efficiency that gradually declined as the plugs wore. While at it, we’ll also inspect the ignition coil boots or spark plug wires (if your engine uses them) and replace those if brittle or damaged. By putting in fresh plugs at ~90k, you set the stage for a smooth-running engine into the 100k+ range. (Remember, cheaper copper plugs would have been changed multiple times by now; the ones in your vehicle have lasted this long by design, but now it’s time!)
     

  • Drive Belt Replacement – If the serpentine belt wasn’t changed yet, it should absolutely be done by 90k. At this point, even if it looks okay, belts fatigue over time and can unexpectedly fail. Installing a new serpentine accessory belt now is cheap insurance. Also, if your engine has any additional belts (for example, some older setups have separate belts for A/C or power steering), those should be replaced as well. You don’t want any original belts going much beyond this mileage.
     

  • Hoses and Cooling System – By 90k, rubber coolant hoses may be showing signs of age. Upper and lower radiator hoses, heater hoses – we will inspect them all carefully. If any feel overly hard (losing elasticity) or have surface cracks visible, it’s wise to replace them now. Likewise, the plastic components of the cooling system (reservoir, radiator end tanks) should be checked for any seepage. If you did a coolant flush at 60k, your coolant should still be in good shape now, but if not, definitely flush it now (5+ years on the same coolant is too long). We want the cooling system to be leak-free and robust, because overheating is one of the killers of high-mileage engines. Think of 90k as a time to renew the cooling system: new hoses, possibly a new thermostat (some people proactively change the thermostat at ~90k to avoid it sticking closed later), and ensuring the radiator is clear of debris. This prep work will help ensure you don’t run into cooling problems as the vehicle approaches the 100k+ zone.
     

  • Fluids Check/Change – Double-check that all fluids have been changed by now. Oil changes are ongoing, but what about the transmission fluid? If it wasn’t done at 60k, do it now – many automatics that went this long on the factory fill will greatly benefit from a fluid change. Differential fluid (in RWD/4x4 vehicles) should be changed by now if not done at 60k or 75k. Transfer case fluid (for 4x4/AWD) as well. Brake fluid should have been flushed already (30k-45k); if not, absolutely do it now again. Essentially, no old fluids should still be in the vehicle after 90k miles – refresh everything so you’re set for the next phase of life.
     

  • Emissions System and Fuel System – Around this mileage, it’s not uncommon for things like the fuel injectors to get a bit dirty, or the oxygen sensors (which measure your exhaust gases) to start aging. Some owners opt to do a fuel system cleaning around 90k – this can involve using a fuel additive or performing a more thorough injector cleaning service to remove carbon deposits. It can help maintain optimal fuel economy and engine performance. Oxygen sensors typically last well over 90k, but by ~100k they can become less responsive, potentially affecting efficiency. We won’t preemptively replace O2 sensors at 90k if there are no engine codes or issues, but it’s something to keep in mind as the vehicle ages (sensors might need replacement if the check engine light comes on for them). We will, however, ensure the PCV system is clean (if your car has a serviceable PCV valve, we might change it now) and that there are no exhaust leaks or emissions-related problems developing. In addition, if your vehicle has a timing chain, at 90k we ensure it’s not loose or creating any rattling noise (timing chains usually last much longer, but we keep an ear out in case a tensioner is weak – though that’s rare at this mileage for GM engines with good oil change history).
     

  • Thorough Inspection of High-Mileage Wear Items – At 90k, the car has seen a lot of use, so we inspect “everything”: wheel bearings, CV joint boots (on front-wheel-drive or independent rear suspensions) for any tears or leaking grease, engine mounts (which can start to crack by this point, causing vibrations), exhaust mounts and pipes (check for rust or damage), and electronics (are all window motors, locks, and other gadgets still working properly?). We also re-check the battery if it was replaced around 60k – by 90k that new battery is maybe halfway through its life. Essentially, any component that could wear out, we keep tabs on now. It’s about ensuring reliability as you head toward the 100,000-mile milestone, where unexpected failures can crop up if maintenance was skipped. Fortunately, if you’ve followed this schedule, you’re in great shape at 90k!
     

Technician Tip: If your vehicle has a timing belt, never push it beyond the recommended interval. We’ve seen unfortunate cases where an owner skipped a timing belt replacement and the belt snapped at ~100k, causing engine valves to bend – a very costly repair. Replacing the timing belt by 90,000 miles is a must on belt-driven engines. It’s a prime example of spending a bit on maintenance now to avoid a massive expense later. If you’re unsure whether your engine has a belt or chain, ask us or check your manual – we’ll make sure you’re on the right track.

After the extensive 90,000-mile service, your Chevrolet or GMC will have received all the critical care it needs as it enters “senior” status (in terms of mileage, not necessarily age!). With a new timing belt (if applicable), new spark plugs, fresh fluids everywhere, and other worn bits replaced, your vehicle is primed to continue running reliably. Many owners notice a difference – the engine might idle smoother or deliver slightly better MPG – simply because those tired spark plugs and filters have been renewed. You’ve essentially hit the reset button on many major maintenance items. Now, it’s time to enjoy the next 10,000+ miles and get ready to join the 100k club!

100,000 Miles – Long-Term Maintenance

Reaching 100,000 miles is a milestone worth celebrating. It’s a testament to your commitment to maintenance and the durability of your Chevrolet or GMC. But the journey doesn’t end at 100k – with proper care, modern vehicles can go well beyond 100,000 miles (it’s common to see 150k, 200k, or more). To ensure your car continues to perform reliably, the 100,000-mile service will address any remaining long-life items and set the stage for the next phase of ownership. Here’s what to focus on at 100k and beyond:

  • Spark Plugs and Ignition (if not already done) – If for some reason the spark plugs weren’t changed at 90k, they must be replaced at 100k. Fresh spark plugs will maximize engine efficiency and prevent misfires in the long run. With those new plugs, your ignition system should be in top shape. At this time, it’s also wise to replace the ignition coil boots (the rubber boots that connect coil-on-plug setups) if they are hardened or cracked, or the spark plug wires in older designs. Basically, refresh anything ignition-related so you have a strong spark for the next 100k.
     

  • Timing Components – By 100k, any timing belt should have been replaced (as discussed in the 90k section). If your engine has a timing chain, while it doesn’t require routine replacement, it’s worth having a technician listen and check for any timing chain rattle or stretch (especially on cold starts). Most likely, a well-maintained chain (with regular oil changes) is fine. But if a chain-driven engine hasn’t had consistent oil changes, sometimes the chain tensioner or guides can wear by this mileage. It’s not common on GM engines that have had good maintenance, but if any symptoms are present (unusual noises), we would address them. Assuming all is well, no action needed – just continue regular oil changes to keep that chain healthy.
     

  • Cooling System Overhaul – At 100k miles, even if you flushed coolant at 60k, it’s probably due for another coolant change (especially if 100k corresponds to about 10 years, which is around the limit for long-life coolants). Additionally, parts like the water pump might be considered for replacement as a preventive measure now if they haven’t been changed yet. Some water pumps last well past 100k, but others might develop slight leaks or bearing wear by this point. If you’re already doing a major service, some owners opt to replace the water pump around 100k to avoid issues. We will inspect it – if there’s any hint of coolant seeping from the pump weep hole or any wobble in the shaft, we’ll install a new pump. Likewise, radiator hoses that survived up to now but are original should be swapped out for new ones (rubber has a finite life). Essentially, making sure the entire cooling system (radiator, hoses, thermostat, water pump, coolant) is fresh at 100k will ward off overheating problems.
     

  • Drive Train Fluids – Another fluid check: if your automatic transmission fluid was changed at 60k, it’s not due yet at 100k (you can wait till ~120k for the next change in that case). But if it was never changed, do it now. Similarly, differential and transfer case fluids – if done at 60-75k, you’re okay; if not, definitely change them now. Brake fluid – should be flushed every 2-3 years, so it likely was done around 90k; if not, do it now. Keeping fresh fluids is an ongoing process even past 100k: continue to flush brake fluid periodically, change coolant every ~5 years or 50k, and transmission fluid every ~50k after the first change, etc., to sustain longevity.
     

  • Suspension and Steering Renewal – Around 100k, a lot of suspension components might be ready for replacement if they haven’t been already. Shock absorbers/struts often don’t last much beyond this mileage – if you haven’t changed them yet and you notice any decline in ride or handling, new shocks/struts will make a world of difference. Ball joints, tie rod ends, and control arm bushings could be worn, causing clunks or vague steering. Replacing those will tighten up the ride. Also, wheel bearings: some wheel bearings can last the life of the car, but others might start humming by 100k. If you hear humming noises that increase with speed or a roughness, a wheel bearing might need replacement. Since these are all safety and drivability related, we’ll inspect and let you know if any are due. A lot of owners of high-mileage vehicles end up doing a “suspension refresh” around 100k – replacing shocks, maybe some bushings or ball joints – to regain that like-new ride. It’s optional if things aren’t too bad, but definitely do any that are clearly worn.
     

  • Exhaust System – By 100k (especially in regions without heavy road salt, like Texas), the exhaust is usually fine. But a quick check for any exhaust leaks or damaged hangers is a good idea. Occasionally, the catalytic converter can start to become less efficient past 100k, which might eventually trigger a check engine light. There’s no maintenance to do on it except to be aware; using good quality fuel and keeping the engine tuned (which you have, with new plugs, etc.) helps the catalytic converter last. If an O2 sensor hasn’t been replaced yet and fuel economy has dropped, sometimes a pre-emptive replacement of upstream O2 sensors at ~100k can slightly help, but it’s not strictly necessary unless they fail or get lazy.
     

  • Continued Preventative Care – The story doesn’t end at 100,000. It’s important to continue regular maintenance beyond 100k. Follow the same patterns: oil changes every 5k, major fluids every ~30k-60k, and keep inspecting belts, hoses, brakes, and tires on a regular basis. Essentially, once you cross 100k, you start over in a sense: many of the items we handled in the first 100k will eventually come due again (for example, if you did a timing belt at 90k, the next one might be due at ~180k if you keep the car that long; spark plugs will go another ~90k, etc.). Modern cars are quite capable of high mileage with this kind of care. In fact, the average car on American roads today is just over 12 years old, which for many drivers means well over 150,000 miles. It’s not uncommon at all to see Chevy and GMC vehicles still running strong at 200,000 miles with diligent maintenance.
     

What maintenance should be done at 100,000 miles?

At 100,000 miles, you should ensure all major maintenance items have been addressed: replace long-life parts like spark plugs (most modern plugs are due by 100k) and any timing belt (if your engine has one, it should be new by now). It’s also wise to flush key fluids – coolant, transmission fluid, brake fluid – if they haven’t been refreshed recently. Inspect or replace the serpentine belt and radiator hoses to prevent any failures. Essentially, by 100k miles, every fluid, filter, belt, and spark plug should have been changed at least once, and wear components like brakes, tires, and suspension parts should be either renewed or in good condition. Following this 100,000-mile service checklist will prepare your vehicle for a reliable life beyond 100k.

With a comprehensive 100,000-mile service behind you, your Chevy or GMC can truly earn the badge of a well-maintained high-mileage vehicle. You’ve traded out all the critical wear items and given it the best chance at a long second life. From here on, maintenance becomes about monitoring and maintaining: stick to the routine intervals (oil changes, etc.), listen and feel for any new developments, and address issues promptly when they arise. Congratulations on hitting 100k – with proper care, there’s no reason you can’t double that if you wish!

Seasonal Maintenance Tips

While mileage-based intervals are a great way to stay on top of maintenance, it’s also important to consider seasonal maintenance – the adjustments and checks your vehicle needs as weather and driving conditions change throughout the year. Corsicana experiences hot summers, mild springs/falls, and occasional chilly winter spells. Prepping your Chevy or GMC for these seasonal shifts will keep you safe and comfortable, and it can prevent weather-related wear. Here are some seasonal maintenance tips and a checklist of items to review as the seasons change:

Summer Prep (Hot Weather)

  • Cooling System: As we discussed, ensure your coolant is fresh and at the correct level. Before the summer heat, it’s wise to inspect for any coolant leaks and make sure the radiator fins are clear of debris. The last thing you want on a 100°F Texas day is an overheating engine.
     

  • Air Conditioning: Test your A/C each spring. If it’s not blowing as cold as it used to, you might need an A/C service (which could involve recharging the refrigerant or fixing a leak). Also, check the cabin air filter before summer – a clean filter will help your A/C cool you down more effectively.
     

  • Battery: High heat can strain your battery. In summer, a weak battery can fail quickly. If your battery is over 3 years old, have it tested as summer approaches. Remember, in hot climates a battery may last only ~3 years on average, so don’t push an old battery into extreme heat if you can avoid it.
     

  • Tires: Check tire pressures when the weather first gets hot. Air expands with heat, so the pressure in your tires can rise in summer. Make sure they’re set to the recommended PSI (when cold in the morning) – overinflation can be an issue in heat, just as underinflation is in cold. Also, summer thunderstorms can be intense, so healthy tread depth is critical to avoid hydroplaning on wet roads. If your tires are worn, consider replacing them before the heavy summer rain season.
     

  • Wipers & Washers: Summer often brings sudden downpours and lots of bugs on the windshield. Check your wiper blades each spring – if they’re streaking or cracked, replace them. Top off your windshield washer fluid too; bug splatter is easier to clean with a good spray of washer fluid and new wipers.
     

Winter Prep (Cold Weather)

  • Battery & Charging System: Cold temperatures can reduce a battery’s cranking power. If heading into winter with a borderline battery, it may leave you stranded on a freezing morning. We advise testing the battery in late fall. Also ensure your charging system (alternator) is functioning well – a healthy alternator will keep the battery charged.
     

  • Antifreeze: Coolant does double duty as antifreeze in winter. If you’ve kept up with coolant changes, you’re likely protected. It’s still smart to check the coolant’s freeze protection level (we have a tool that measures this) before winter. This ensures the coolant mixture will resist freezing in any unusually cold weather. Corsicana doesn’t often see severe sub-zero temps, but being protected to 0°F or below is a good idea just in case of an unexpected freeze.
     

  • Tire Pressure: Tire pressure drops in cold weather (about 1 PSI for every 10°F drop in temperature). When the first cold fronts arrive, check and adjust your tire pressures. Those TPMS (tire pressure monitoring system) warning lights tend to pop on when the weather changes – a quick top-off of air will resolve that and ensure proper traction and tire wear.
     

  • Heater and Defrosters: Make sure your heating system is working properly. This is not just for comfort, but for safety – a functional defroster is needed to keep your windshield clear of fog or frost. Test your front and rear defrost before truly cold nights hit. If the defroster isn’t doing the job, it could be an AC issue (the AC helps dehumidify air for defogging even when set to warm) or a coolant flow issue to the heater core. We can diagnose and fix any heating problems so you stay warm and your windows stay clear.
     

  • Oil Viscosity: This is less of an issue nowadays because modern multigrade oils handle a wide range of temperatures. But ensure you’re using the manufacturer-recommended oil viscosity. For example, 5W-30 synthetic might be recommended year-round. That “5W” part means it flows well in winter (W = winter). If for some reason you have a much thicker oil in the engine, consider switching to the recommended grade before winter for easier cold starts. (This is usually only a concern if someone deviated from spec; if you maintain with us, we always use the right oil, so you’re fine.)
     

  • Emergency Kit: Not a maintenance item per se, but it’s wise to carry a winter emergency kit if you travel out of town. Include things like jumper cables, a flashlight, basic tools, a blanket, and some flares or reflective triangles. While Corsicana winters are mild, if you drive into northern areas or get caught in a rare ice event, you’ll be glad to have supplies.
     

Rainy Spring/Fall

  • Wiper Blades: Replace them annually, typically in the fall or spring. This ensures you have fresh wipers for the wetter seasons.
     

  • Tire Check: Again, check tread depth and pressures. Wet roads from spring showers or autumn storms require good traction. Rotate your tires if it’s time (to keep tread wear even for maximum grip).
     

  • Leaks: After dry summers, sometimes the first fall rains can reveal leaks (for example, old weatherstripping might drip water into the cabin). Keep an eye out for any moisture where it shouldn’t be. Also, ensure your exterior lights (headlights, brake lights) are all working – dark, rainy commutes require full visibility and signaling.
     

  • Alignment: Fall is a good time to consider an alignment check, especially if you plan on doing holiday road trips. Potholes from summer or unseen bumps in rainy weather can knock things out. Proper alignment helps during those long drives and in slick conditions.
     

In summary, adapting your maintenance routine to the seasons will complement your mileage-based schedule. Most of these seasonal checks are simple and coincide with your regular service visits – for example, when you come in for an oil change in late spring, that’s a perfect time for us to inspect the A/C and cooling system for summer. Or your pre-winter oil change can include a battery test and coolant check. We encourage Corsicana drivers to use the changing seasons as reminders to address weather-specific maintenance needs.
