How often should the belt next to the car engine be replaced?

[SanLeo]

Car engine belts should be replaced approximately every 60,000 to 80,000 kilometers. The replacement cycle for engine belts varies among different vehicle models. Once exceeding 50,000 kilometers, regular inspections are recommended to promptly detect any abnormalities in the timing belt, primarily by listening for unusual sounds. Signs of wear or abnormalities often manifest as abnormal noises or unusual odors caused by wear. The timing belt is a crucial component of the engine and plays a key role in its normal operation. It is an essential part of the engine's valve system, connecting the crankshaft and camshaft to ensure the accurate timing of intake and exhaust through a specific transmission ratio. If the timing belt fails, the valves and ignition system will cease to function, and in severe cases, the cylinder head may also be damaged.
