What are the hazards of engine overheating?

[VanPenelope]

Engine overheating can cause the following hazards: Engine overheating leads to a decrease in engine power, further reducing the engine's air charging efficiency. This results in a reduced amount of fresh air-fuel mixture entering the cylinders, lowering the average effective pressure in the cylinders, and may also cause damage to the engine head gasket. Extension: 1. Engine head gasket damage: Damage to the engine head gasket can allow engine oil to enter the combustion chamber, leading to oil burning. It may also cause engine oil to mix with coolant, rendering the coolant ineffective. In severe cases, the entire cooling system may need to be replaced. 2. Thermal deformation of engine components: Engine overheating can cause many components to deform due to thermal expansion, such as the cylinder head and engine block (currently, many cylinder heads and blocks are made of aluminum). In severe cases, this may lead to complete engine failure.
