What is the Replacement Interval for a Car Engine Belt?

[VanRuby]

Car engine belts should be replaced every 60,000 to 80,000 kilometers. When a vehicle exceeds 50,000 kilometers, the timing belt should be inspected to promptly identify any abnormal conditions. The function of a car engine belt: It transmits the force from the crankshaft to drive components such as the water pump and alternator. Steps to replace a car engine belt: 1. Lift the car with a jack; 2. Remove the engine undercover; 3. After removing the undercover, the alternator belt will be visible; 4. Remove the exposed old alternator belt; 5. Install the new engine belt; 6. The engine belt replacement is complete.

I've been driving for over a decade, and the replacement interval for engine belts is typically every 60,000 to 100,000 kilometers or 5 to 7 years. It depends on your car's brand and specific model. For example, my old Honda's manual recommends replacing the timing belt every 80,000 kilometers, while some German cars may require earlier replacement. A friend of mine discovered cracks in the belt at 60,000 kilometers but didn't replace it in time, resulting in a snapped belt on the road that destroyed the engine internals, costing over 20,000 yuan in repairs. I suggest having a technician check the belt's condition during regular maintenance to look for cracks or looseness. If any abnormalities are found, address them promptly. Don't forget that harsh driving conditions like high temperatures or dusty roads can accelerate aging. Replacement costs usually range from 500 to 1,500 yuan—don't try to save money by doing it yourself; professional shops are more reliable. Timely replacement not only saves money but also ensures safety.
