What are the causes of high temperature in car engines?

[DeDawson]

The causes of high temperature in car engines include fan issues, exhaust problems, coolant leakage, and pump problems. Fan issues: The fan motor may not operate or the fan clutch may malfunction, preventing proper cooling. It is recommended that the owner inspect and repair the motor and fan clutch. Exhaust problems: A blocked catalytic converter or a ruptured pipe can lead to exhaust obstruction, causing the engine to overheat. Owners are advised to repair the pipes. Coolant leakage: If the cooling system's pipes are ruptured, coolant loss occurs, and heat dissipation fails to function properly. This situation can be resolved by replacing the damaged pipes. Pump problems: After prolonged use, the pump may experience significant wear, with parts wearing out or breaking off. The only solution is to replace the pump with a new one. When the engine temperature is excessively high, the lubricating oil that enters the cylinders can form carbon deposits under high-temperature and oxygen-deficient conditions. These deposits accumulate on the piston top, combustion chamber walls, valve tops, and spark plugs, creating hot spots that can lead to pre-ignition and abnormal combustion. This can cause deformation of the engine block and cylinder head, and may even result in cracks or warping. Additionally, it can burn out the cylinder head gasket, leading to reduced cylinder pressure at the end of compression and increased fuel consumption.
