What are the causes of engine overheating?

[DeAnthony]

Causes of engine overheating include the following points: 1. Fan issues: The fan motor is not working or the fan clutch is faulty, preventing proper cooling and leading to engine overheating. 2. Exhaust: A blocked catalytic converter or a broken pipe causes exhaust obstruction, resulting in engine overheating. Additionally, a mismatch between the updated thermostat and the original temperature coefficient can be a fault cause. 3. Thermostat blockage: The thermostat cannot open or close properly, usually due to mechanical failure or incomplete filling of the cooling system. A mismatch between the updated thermostat and the original temperature coefficient can also cause faults. 4. Coolant leakage: If there is a crack in the cooling system pipes, coolant loss occurs, and heat dissipation cannot function properly. 5. Water pump: After prolonged use, a highly worn water pump may have parts that are worn out or detached. 6. Radiator cap: If the radiator cap pressure is uneven, it can cause the spring to loosen, preventing the cap from sealing tightly.
