Common Causes Of Car Engine Overheating:
A Coolant Leak:
Coolant is responsible for keeping your engine temperature down. Coolant will escape if there's a leak in the system, and your engine will be left without any protection against overheating. A coolant leak can be induced by many things, including a faulty radiator cap or water pump, a cracked hose, or a leaking gasket.
A Dirty or Blocked Cooling System:
If your cooling system is full of dirt and grime, it won't be able to do its job properly. The same goes for a cooling system that's been blocked by debris. Over time, this can lead to engine overheating.
A Broken Fan:
The engine cooling fan is responsible for drawing air through the radiator to keep the engine cool. If the fan is broken or not working properly, it won't be able to do its job, and the engine will overheat.
A Clogged Radiator:
If the radiator is blocked with debris, it won't be able to cool the engine properly. A clogged radiator can also be caused by a build-up of rust or scale inside the radiator.
A Seized Water Pump:
The water pump in your automobile may fail, causing the coolant motive force to vanish rapidly, permitting the water in the engine to heat up rapidly and perhaps causing your engine to overheat.
A Faulty Thermostat:
If the thermostat in your car is stuck in a closed position, it will cause the engine to warm up and then keep heating. No matter how hot the engine gets, the coolant cannot pass through, causing your engine to overheat.
A Low Coolant Level:
Heat is extracted from the engine through a coolant. If the coolant level in your car is low, it can cause overheating. Check the level of coolant regularly and up if necessary.
How to Fix an Overheating Car Engine?
If your engine overheats, it is important to take action immediately to avoid damaging the engine. Pullover and turn your car off. Allow it to cool down before opening the hood.
Check the coolant level once the car has cooled down and add more if necessary. If you don't have coolant, you can use water but make sure to bring the car to a mechanic soon and get it fixed.
Your car is a complex machine, and many things can go wrong. If your car is overheating, it's crucial to take it in for service as soon as possible.
