What to Do About Abnormal Noise from the Car Alternator Belt?
1 Answers
Replacing it with a new one is the best option. There are many reasons for alternator belt noise: 1. One is a belt issue, another is the belt tensioner, and there's also belt slippage; 2. In most cases, it can also occur when the engine is hot, as long as the noise is not too loud, it can be ignored and won't affect the belt's lifespan; 3. Aging of the drive belt can cause a 'squeaking' sound during vehicle startup, because the main component of the drive belt is rubber, especially in winter when rubber becomes hard and brittle, reducing the friction coefficient; 4. If the belt is excessively worn, it can also produce a 'squealing' sound. Since the belt is made of rubber, aging reduces friction, making it unable to transmit power effectively, leading to slippage;
