What Happens When a Car Engine Overheats?

[John]

Engine overheating can lead to a decrease in engine power, further reducing the engine's air charging coefficient, which results in a reduced amount of fresh air-fuel mixture entering the cylinders and a lower average effective pressure in the cylinders. It can also cause damage to the engine's cylinder head gasket. If the cylinder head gasket is damaged, coolant may enter the combustion chamber and participate in combustion, with a certain probability of bending the connecting rod. Causes of engine overheating include: 1. A malfunctioning cooling system fan leading to high engine temperature. 2. A stuck thermostat in the engine cooling system causing high engine temperature. 3. A damaged water pump in the engine cooling system resulting in high engine temperature. 4. Excessive dirt on the radiator surface of the engine cooling system leading to poor heat dissipation and high engine temperature.
