What Causes a Car Engine to Overheat

If you’re like most drivers, you’re probably aware of the dangers of over-heating your engine. But what are the actual causes of an engine overheating, and how can you avoid it? Read on to learn more.

What Causes an Engine to Overheat?

When an engine overheats, it can cause permanent damage. Overheating can be caused by a variety of factors, including a broken thermostat, a clogged radiator, or a faulty cooling system. Here are five common causes of engine overheating:

1. A broken thermostat: A thermostat is a device that regulates the temperature in an engine. When it malfunctions, the engine can overheat.

2. A clogged radiator: A clogged radiator is one of the most common causes of engine overheating. This problem occurs when particles build up in the radiator and prevent the water from circulating freely.

3. A faulty cooling system: If the cooling system isn’t working properly, the engine can overheat. This includes everything from a blown fan belt to a cracked block.

4. Failed evaporation: Evaporation is one of the primary methods engines use to cool themselves down. If there’s something blocking this process, the engine will overheat.

5. Fuel starvation: If there’s not enough fuel available to the engine, it will struggle to keep itself cool and will overheat.
