As the temperature rises, so does the risk of vehicle problems. Don’t get stranded on the side of the road with a preventable breakdown. A little preparation now can save you a lot of time and money later. This guide covers essential checks to ensure your vehicle is ready to handle the heat.

1. Coolant System Check

Your engine’s cooling system is the first line of defense against summer heat. A malfunctioning system can lead to overheating and catastrophic engine damage.

• Check Coolant Levels and Condition: The coolant (antifreeze) prevents your engine from overheating. Make sure your reservoir is filled to the proper level. The fluid should be a vibrant color (usually green, yellow, or red/pink). If it looks murky or has rust particles, it needs to be flushed and replaced.
• Inspect Belts and Hoses: Hoses can become brittle or cracked from heat exposure, while belts can fray or slip. Squeeze the hoses; they should feel firm, not soft or spongy. Check belts for cracks, fraying, or missing chunks. A broken belt can cause your engine to overheat, and you might lose power steering and other functions.

 

2. Tire Care and Maintenance

Heat can increase the pressure inside your tires, making them more susceptible to blowouts.

• Check Tire Pressure: As temperatures rise, so does the air pressure in your tires. Always check your tire pressure when the tires are cold (before driving) and inflate them to the manufacturer’s recommended PSI, which is listed on a sticker inside the driver’s side door jamb, not the number on the tire’s sidewall.
• Inspect Tire Tread: Use the penny test to check your tire tread. Place a penny upside down into a tire groove. If you can see all of Lincoln’s head, your tires are worn and need to be replaced.
• Tire Rotation: Get your tires rotated every 5,000-7,000 miles to ensure even wear and extend their lifespan.

 

3. Battery Check

Believe it or not, high summer heat is harder on your car battery than cold winter weather.

• Check for Corrosion: Heat can accelerate the corrosion on battery terminals. A powdery, bluish-green substance on the terminals can hinder the battery’s ability to charge. Clean it off with a wire brush and a solution of baking soda and water.
• Test Battery Life: A professional can test your battery’s charge and overall health. Most batteries last 3-5 years, so if yours is nearing that age, it’s wise to have it checked.

 

4. Fluid Checks

Just like your body, your car relies on various fluids to operate smoothly.

• Engine Oil: Check your oil level and color. Clean oil is a transparent amber color. If it’s dark and dirty, it’s time for an oil change. Oil is your engine’s lifeblood, and it breaks down faster in hot weather.
• Windshield Washer Fluid: You’ll use this more often to clear bugs and road grime. Make sure the reservoir is full.
• Brake Fluid: Brake fluid is crucial for your vehicle’s stopping power. Check the level, and if it’s low, have a professional inspect for leaks.

 

5. Air Conditioning System

Driving in a sweltering car is unpleasant and can even be dangerous.

• Test the A/C: Turn on your A/C and make sure it blows cold air. If the air isn’t cold enough or the airflow is weak, you may need an A/C recharge or repair.
• Inspect Cabin Air Filter: A clogged cabin air filter can reduce your A/C’s performance and introduce allergens into the car. This is a simple and inexpensive replacement that makes a big difference.
