Introduction: Beat the Heat Before It Beats Your Car
Texas summers aren’t just hot—they’re relentless. When the temperature climbs into the triple digits, your vehicle can turn into an oven in minutes. Whether you drive a Chevrolet Silverado, GMC Terrain, or anything in between, managing the heat is about more than comfort—it’s about protecting your vehicle, your passengers, and your investment.
At Chevrolet GMC of Corsicana, we know what Texas heat does to cars. Our service team sees it every year: dead batteries, stressed A/C systems, cracked dashboards, and overheating engines. The good news? With a few smart habits and routine care, you can keep your Chevrolet or GMC cool and running strong all summer long.
Why Summer Heat Is Hard on Vehicles
Before we dive into the how-to, let’s talk about why high temperatures are such a challenge for your vehicle:
-
Cabin temperatures can exceed 140°F in direct sun
-
Rubber parts like hoses and belts become more brittle and prone to cracking
-
Battery capacity is reduced faster in extreme heat
-
A/C systems work overtime, leading to wear and tear
-
Engine coolant and fluids evaporate or degrade more quickly
In other words, summer isn’t just about rolling down the windows—it’s about staying ahead of problems that heat can create under the hood and inside your cabin.
1. Stay on Top of A/C Maintenance
Your air conditioning system is your first line of defense against the summer heat. If it’s not cooling like it used to—or it takes forever to get cold—it’s time to have it checked.
Signs your A/C may need service:
-
Weak airflow, even on max fan setting
-
Cool air takes too long to kick in
-
Musty or odd smells from the vents
-
Clicking or rattling sounds when the A/C is on
At our Chevrolet service center, we offer complete A/C inspections and can recharge or repair your system with OEM parts made for your Chevy or GMC. It’s best to do this before the first major heatwave hits.
2. Park Smarter, Not Hotter
It may seem like common sense, but parking in the shade can dramatically reduce the heat inside your car. If a covered spot isn’t available, use a reflective windshield sunshade to block UV rays and trap less heat inside the cabin.
Other smart tips:
-
Crack your windows slightly to allow hot air to escape
-
Use a towel or dash cover to protect interior plastics
-
Consider tinted windows, which can block up to 70% of solar heat
-
Point your air vents upward before leaving your vehicle to help hot air rise and circulate faster
Little changes in how and where you park can make a big difference when you return to your vehicle.
3. Keep an Eye on Coolant Levels and Radiator Health
One of the most critical systems for keeping your car cool is your coolant system. Coolant (or antifreeze) circulates through your engine and radiator to keep everything at a safe operating temperature.
During summer, it’s vital to:
-
Make sure coolant levels are within range
-
Inspect for leaks around the radiator or hoses
-
Look for signs of corrosion in your coolant reservoir
-
Ensure the radiator fan is working correctly
Low coolant is one of the most common causes of summer breakdowns. If you're not sure when your last flush was, schedule a service appointment through our online scheduler, and we’ll take care of it.
4. Don’t Overload Your Vehicle
Summer often means road trips, camping, and hauling boats or trailers—but that extra weight can place added stress on your engine, transmission, and A/C system.
Tips for smarter summer hauling:
-
Check your Chevy or GMC’s towing capacity in the owner’s manual
-
Use trailer brakes when needed
-
Keep your tires properly inflated (including your trailer)
-
Avoid overloading your trunk or roof rack
If you're planning to tow this season, ask about our multi-point inspection at your next visit to make sure your vehicle is summer-ready.
5. Use Remote Start to Pre-Cool the Cabin
If your Chevrolet or GMC has a Remote Start, use it to your advantage. Starting the engine a few minutes before you enter allows the A/C system to kick in and cool the interior—especially helpful when your vehicle’s been baking in the sun.
Bonus tip: Set your climate controls before shutting off your car so the air starts flowing immediately the next time you remote-start it.
If your vehicle doesn’t have Remote Start, ask our team about aftermarket installation options—we offer upgrades on many models.
6. Swap Out Your Cabin Air Filter
Your cabin air filter helps purify the air that comes through your vents. In summer, a dirty or clogged filter reduces airflow, making it harder for your A/C to keep up.
We recommend replacing it at least once a year—or more often if you live in a dusty area, drive on gravel roads, or experience seasonal allergies. It’s a fast, inexpensive service that makes a noticeable difference.
Learn more about our certified parts and filter replacement services on our Chevrolet service page.
7. Stay on Schedule With Preventive Maintenance
Routine service is your best defense against heat-related breakdowns. Your owner’s manual includes recommended service intervals for:
-
Oil changes
-
Coolant flushes
-
Battery testing
-
Belt and hose inspections
-
A/C system checks
Don’t wait for something to go wrong—be proactive. You can easily schedule maintenance online, and our team will help you get everything squared away before the heat gets worse.
