Cooling fan malfunction: The cooling fan helps to dissipate heat from the engine. If the cooling fan is not working properly, it can lead to overheating.
Water pump failure: The water pump circulates coolant around the engine to help dissipate heat. If the water pump fails, the coolant will not be able to circulate properly and the engine will overheat.
Radiator leak: A leak in the radiator can cause the coolant to leak out. This can also lead to overheating.
Cylinder head gasket failure: A blown cylinder head gasket can allow coolant to leak into the engine oil. This can lead to overheating, especially when the engine is under heavy load.
Low coolant level: If the coolant level is too low, the engine will not be able to cool itself properly. This can lead to overheating.
Faulty temperature sensor: A faulty temperature sensor may send incorrect readings to the engine's computer. This can cause the engine to run hotter than it should, leading to overheating.
