Does a broken fan belt and high temperature affect the engine?

[CooperLee]

A broken fan belt does affect the engine. The belt breaking will reduce the engine's cooling efficiency, and abnormal noises may lead to serious engine failures. It is likely to damage components such as pistons, the engine block, and valves. 1. Engine timing belt (Timing-belt): It is an important part of the engine's valve system, ensuring accurate intake and exhaust timing by connecting to the crankshaft and maintaining a specific transmission ratio. The use of a belt instead of gears for transmission is because belts produce less noise, offer precise transmission, have minimal self-variation, and are easier to compensate. Obviously, the lifespan of a belt is shorter than that of metal gears, so it needs to be replaced regularly. 2. Replacement interval: The engine belt should be replaced every 60,000 kilometers. If the engine timing belt shows signs of aging or breaking, it should be replaced promptly. Failure to do so may result in poor engine performance and, in severe cases, engine failure.
