What happens when your car overheats?

car temperature gauge

Overheating happens when the engine reaches higher temperatures (generally above 100 degrees Celsius). This can happen for several reasons, but it can usually be attributed to a problem in your cooling system. Overheating can be detected by looking at your car’s temperature gauge. 

When your car overheats, engine components such as the head gasket or cylinders are prone to cracking or warping. For this reason, it is not recommended that your drive an overheating vehicle. The cost of a tow truck will be much less than the cost of an engine replacement!

Common causes of overheating:

There are several different things that can cause your car to overheat, with most of these things resulting in your engine being starved of oil or coolant. Common symptoms of overheating include:

Damaged thermostat – The thermostat detects your engine temperature and opens/closes to let coolant into your engine. If the thermostat becomes stuck shut, coolant won’t be able to reach the engine, resulting in it overheating.

Coolant leak – A leak in your cooling system can starve your engine of coolant, resulting in overheating. Coolant leaks can be diagnosed by looking for small puddles underneath the front of your car.

Low oil levels – A car that is low on oil can be prone to overheating. This is because oil helps to carry heat away from the engine. Low engine oil can also cause increased engine wear due to the moving parts not being lubricated properly. This can also cause overheating.

Broken water pump – The water pump helps to pump the coolant through the engine. If anything goes wrong with the water pump, your engine will not receive the necessary amount of coolant and overheat.

Very hot weather – In some cases, if the weather is very hot and your cooling system is partially blocked, this can cause your temperature gauge to rise higher than normal. 


What to do if your car overheats?

If your car’s temperature gauge is reaching high levels, try to avoid driving until your vehicle can be repaired. Overheating will damage your engine, especially if you continue to drive normally.

Examining your coolant may help you diagnose the problem. However, you should never remove the radiator cap while the car is still warm. Let the car cool down for a few hours to avoid burns and injuries.
