Man Looking Under a Car's Hood

As the weather gets warmer, there are new car problems to watch out for. Although it’s not exclusive to warm weather, a car overheating is a common issue to have around this time of year. There are a variety of reasons that your car might overheat. Today in the Thompson Sales blog, we’ll talk about some of these reasons.

Issues with Coolant of Cooling System

The most common reason your car engine overheats is when there’s something wrong in the engine compartment. Your cooling system might have a leak, or a hose might be blocked. These issues can both make it hard for your cooling system to keep your engine at an ideal temperature. Luckily, both of these issues can easily be fixed by a mechanic.

You can even temporarily seal a leak on your own until you can get it into a repair shop. Your coolant is also essential to keeping your engine from overheating. If you have the wrong coolant or your ratio is off, this can cause problems. Make sure to check this if you’re having overheating problems.


If you have an older battery, your car has to work harder to keep your engine cool. Replacing your battery could be the right solution.


Oil helps to keep your engine and all its systems running properly. If you have low oil, it’s possible that your engine isn’t able to run well enough to keep itself cool.

These are just a few reasons your car might overheat. If you’re having overheating issues, it’s best to bring your vehicle to a mechanic to make sure everything is working before driving again.

What to Do if Your Engine Overheats

If your engine does overheat, you need to take action immediately to prevent further damage. If you see the temperature gauge go up too far or if an indicator light comes on, take the following steps.

  1. Turn off your A/C and open the windows
  2. Pull over and turn on your hazard lights
  3. Turn your heater on to take heat out of the engine area
  4. Open the hood
  5. Do NOT touch the radiator cap. It will be dangerously hot from the engine being overheated
  6. Wait until the temperature gauge goes down
  7. Check for the issues we talked about earlier
  8. Take your vehicle to a mechanic as soon as you can

Following these steps will ensure you get your engine fixed without doing any more damage to the system.
