Summer Car Maintenance Tips for Texas Heat

When summer hits Texas, the temperatures don’t just rise—they soar. In McKinney and the surrounding North Texas communities, it’s not uncommon for asphalt-melting heat to push cars to their limits. Whether you’re commuting daily, planning a road trip, or just running errands around town, it’s crucial to make sure your vehicle is ready to handle the intense Texas summer heat.

At Tomes Auto Group, we’re here to help you stay safe on the road. Here are essential summer car maintenance tips to protect your vehicle, and your wallet from the extreme Texas heat.

1. Check Your Cooling System

Your car’s cooling system is the first line of defense against overheating. In hot climates like McKinney, TX, it’s especially important to:

• Inspect coolant levels and top them off if needed

• Flush and replace old coolant (recommended every 2 years or 30,000 miles)

• Check hoses for cracks or leaks

• Ensure your radiator fan is working properly

Stop by our service center in McKinney for a quick cooling system inspection before the next heatwave hits.

2. Test Your Battery

High heat can cause your battery fluid to evaporate, which leads to internal corrosion and shortens battery life.

• Get your battery tested to check for wear

• Clean any corrosion around the terminals

• Ensure the battery is securely mounted

Our technicians at Tomes Auto Group can test your battery and replace it if needed—no appointment necessary.

3. Inspect Tires and Tire Pressure

Tires can expand in the heat, which may lead to blowouts on scorching Texas roads.

• Check tire pressure weekly (including the spare!)

• Look for worn treads or sidewall damage

• Consider switching to summer-rated tires if you’re due for a replacement

We’re conveniently located in McKinney, just a short drive from Allen, Frisco, and Plano for all your tire service needs.

4. Replace Worn Wiper Blades

Summer doesn’t just bring heat—it brings sudden thunderstorms too. Don’t let worn blades ruin your visibility.

• Inspect wipers for cracks or streaking

• Replace blades every 6–12 months

We carry high-performance wiper blades that are perfect for Texas weather.

5. Stay on Top of Oil Changes

Engines work harder in the heat. Fresh, high-quality oil helps maintain engine temperature and performance.

• Follow your manufacturer’s recommended oil change schedule

• Use the correct oil type for high temperatures

Our quick-lane oil change service in McKinney gets you back on the road fast.

6. Test Your Air Conditioning System

You don’t want to discover your A/C isn’t working when you’re stuck in traffic on Highway 75 in 105°F heat.

• Check that cold air is coming out quickly

• Listen for unusual noises or weak airflow

• Have your system recharged or serviced if needed

We offer full A/C diagnostics and repair to keep you and your passengers cool all summer long.

7. Clean and Protect Your Interior

UV rays and high heat can cause your dashboard, leather seats, and interior panels to crack or fade.

• Use sunshades and window tints

• Apply UV protectant to surfaces

• Consider ceramic coating or interior detailing
