Seven Common Causes of Engine Overheating

Seven Common Causes of Engine Overheating

Keeping your engine cool requires a lot of different components to work properly, and even a single one dropping out or slowing down could lead to a pretty serious problem when the engine starts to get just a little too warm. Here are seven of the most common reasons why your engine could start overheating.

1. Coolant Leaks
Coolant (or antifreeze) is designed to keep your engine from freezing in winter and boiling in summer. It’s also used to prevent overheating by transferring heat away from the engine. This means you need to keep an eye on your coolant levels, which you can usually find in a tank near the top of your engine bay. A low level suggests a leak, which needs repaired quickly.

2. Insufficient Radiator Fans
If you’ve recently replaced your radiator or the fan connected to it, you may not be pulling enough air through to cool your engine. Replacing it might prove to be difficult, so you should speak with a Katy high performance automotive expert about it.

3. Damaged Radiator
Related to the previous point, your radiator fan will only do so much if the radiator itself is broken. Bent fins, dents, and other obstructions prevent a radiator from keeping your car cool and running smoothly, which can lead to overheats fairly quickly.

4. Broken or Worn-Out Belt
The serpentine belt that runs through your car is designed to keep your engine running smoothly, including turning your alternator, water pump, and more. If this belt breaks or wears out, your water pump will stop working, which will quickly cause your engine to overheat.

5. Broken Thermostat
The thermostat in your engine has two different functions: preventing coolant from getting into your engine when it’s cold and opening the coolant chamber when it gets too hot. When the thermostat goes bad, your engine will run fine but then spike in temperature quickly.

6. Broken Water Pump
As stated previously, the serpentine belt drives the water pump amongst several other things. However, when this water pump goes bad, you could still face a similar problem. Make sure you periodically check to make sure your water filter is working as intended.

7. Low Oil
Your engine has oil in it to reduce friction between the pistons, rods, and other joints as they rub against each other. However, it also has a secondary benefit: it removes heat from the engine as it cycles through. If your engine oil gets low, not only will you not have this benefit of heat removal, but you’ll also risk having the parts rub against each other, which creates friction and heat quickly.
