You don’t have to leave all the fun to the experts. If you’re a DIY-er, you can do this stuff on your own:

1. Check your oil

Oil helps keep your engine lubricated, which reduces friction (and heat buildup) under your hood. During the summer, when your engine is more likely to overheat, it’s going to want as much lubrication as it can get.

But checking your oil is super easy. And if you’re low, adding more oil is easy too. Just don’t confuse adding oil with changing oil. You should still get an oil change every 5,000 miles or so.

2. Heck, check all your fluids

If you remember back to high school chemistry, heat causes liquid to evaporate. And all those fluids in your car have very important jobs to do, like lubricating and cooling.
Topping off your fluids at the start of the summer can help you avoid overheating. If you’re unsure about which fluids to use or how much to add, ask your mechanic for help.

3. Inspect your tires

As outside temperatures fluctuate, so does tire pressure — cold temperatures cause tire pressure to drop while hot temperatures cause it to increase.
So, first things first: make sure your tires are properly inflated. You can usually find your tire’s recommended PSI (pounds per square inch) in your owner’s manual or on your driver’s side door. To ensure an accurate measurement, always make sure you haven’t driven for at least 3 hours.
Keep in mind that improper inflation can affect your car’s handling. Under inflated tires are especially problematic because they tend to lower your gas mileage and wear down quicker. In more extreme cases, the combination of heat and low pressure can cause your tire to blow.
Also, check your tires for damage and wear. Hot roads can intensify heat buildup and cause weak tires to weaken even faster, especially if they’re not properly inflated.

4. Wash and wax your car

Keeping your car shiny and clean may seem like an unnecessary expense, but it can actually save you from major costs down the road. Dirt and dust scratch away at your car’s top coat … you know, the one that protects the paint from fading and peeling in the sun.
Paint damage is more than just unsightly, though — it can actually be damaging to your car’s structure. When paint peels away, it leaves your car susceptible to rust.

If you don’t drive often, you may want to consider covering your car. A cover will protect it from sun and other corrosives like sap and bird poop, which get even more corrosive in the heat.
