What Are the 10 Common Causes of Car Overheating?

A car overheating is one of the common problems car owners and drivers face. The cooling system of your car is always under pressure and high temperature that may cause engine overheating problems over time.

Here are ten common causes that lead to a car engine overheating:

1. Leaks in the Cooling System

If you have a leak in the cooling system of your car, the coolant drips through the puncture, and air enters the system through the leak. This causes an airlock in the cooling system and makes it difficult for the coolant to push through the system to reach the engine, thus causing it to overheat.</p

2. Incorrect Coolant Concentration

Always use the correct type of coolant in your vehicle as well as remember to use the right mixture of coolant and distilled water.

3. Loose Coolant Hose Clamp

Having a loose clamp on your car coolant hose can also be a reason for engine overheating. The clamps tend to loosen up or even break over time, so be sure to replace them when you notice it loosening.

4. A Faulty Thermostat

If you have a faulty thermostat that remains closed, the coolant will not be able to pass through the system. This can result in your car engine overheating.

5. Clogged or Cracked Car Radiator

A car’s radiator pulls heat away from the rest of the cooling system. If it is not working correctly due to leaks and clogging, it can lead to car overheating.

6. Worn Out or Burst Hoses

Hoses that are worn out or have cracks will leave you with a leaky engine that will obstruct the coolant’s flow through the system and cause car overheating.

7. Bad Radiator Fan

The primary function of a radiator fan is to pull air across the radiator to help reduce the coolant’s temperature. Therefore, if you have a faulty radiator fan, it will lead to engine overheating.

8. Loose or Broken Belts

If a belt is loose or broken, it will not maintain the correct volume of coolant flow and cause overheating.

9. A Faulty Water Pump

A water pump is often considered as the heart of your cooling system. If it’s not operating correctly, it can cause your vehicle to overheat.

10. Low Oil Level

Engine oil helps with the cooling process and avoids the buildup of excessive heat. It also keeps various parts of the engine properly lubricated, reduces friction, and overheating. So, your car can overheat if your oil levels are low.
