What is the replacement interval for a car engine belt?

[LaChristian]

The replacement interval for a car engine belt varies depending on the vehicle model. Generally, the timing belt should be replaced every 60,000 to 80,000 kilometers, while high-quality belts can last up to 100,000 kilometers. Once the mileage exceeds 50,000 kilometers, it is advisable to inspect the timing belt regularly for any abnormalities, primarily by listening for unusual sounds. Typically, signs of wear will manifest as abnormal noises. The exact replacement time should be referenced in the car's maintenance manual. The timing belt is a crucial component of the engine and plays a key role in its proper operation. As an essential part of the engine's valve system, it connects the crankshaft and camshaft to ensure the precise timing of intake and exhaust through a specific transmission ratio.
