How often should the car alternator belt be replaced?

[StAngela]

Car alternator belts should generally be replaced every 60,000 to 80,000 kilometers, with some capable of lasting 80,000 to 100,000 kilometers. It's important to regularly inspect the belt's condition as it approaches the replacement interval. Replacement is also necessary if any of the following conditions occur: 1. The belt core is broken or the groove section is cracked; 2. The belt's covering layer separates from the tension cords or the cords become frayed. In an engine, the belt drives various auxiliary components such as the air conditioning compressor, power steering pump, and alternator. If the belt breaks or slips, it will cause these auxiliary components to lose functionality or reduce their performance, affecting the vehicle's normal operation.
