What Causes a Car Belt to Squeak?
1 Answers
There are several reasons why a car belt may squeak: Belt slipping: This could be due to the belt slipping on the alternator, causing intense friction and vibration between the belt and the pulley, resulting in a noise at a certain frequency. The main causes of belt slipping are a loose or worn-out belt. Factors that can lead to a loose belt include improper adjustment of the belt tensioner or insufficient tensioner spring force. In such cases, the first step is to adjust the tension of the belt tensioner. If this doesn't resolve the issue, the tensioner should be replaced. Belt aging: This primarily refers to the belt gradually hardening and losing elasticity over prolonged use, which reduces friction between the belt and the pulley. In this scenario, the only solution is to replace the belt.
