What are the signs that indicate the need to replace the generator belt?
2 Answers
Generator belt needs to be replaced when the following signs appear: Abnormal noise from the generator belt: This situation is caused by the engine belt being too loose or the installation position being uncertain. It is best to check promptly if a slipping or grinding sound is heard. Cracks, fissures, and peeling of the generator belt: This condition may result from incorrect installation leading to uneven force distribution, corrosion, or simply prolonged use causing the engine belt to age and harden. Excessive usage time: Generally, the service life of an engine belt is 2 years or 60,000 kilometers. Therefore, it is necessary to replace it when the specified usage period is reached. Never wait until it breaks to replace it, as this can easily lead to dangerous situations.
Last month, my car developed a squeaking noise, especially noticeable during cold starts. Later, I discovered it was a sign of wear on the alternator belt. As an experienced car owner, I know this belt drives the alternator and sometimes the water pump. Upon inspection, I noticed fine cracks and slack in the belt. If not replaced promptly, the noise would grow louder, and the belt could snap, causing the alternator to stop working, draining the battery, and leading to a dangerous stall. I quickly took it to the repair shop for a replacement, which cost around 200 to 300 RMB. Now, it's much quieter. I recommend regularly lifting the hood to check the belt for cracks or oil contamination. If you hear any noise, take action immediately—don’t wait until you’re stranded on the road to regret it.
