What Causes the Squeaking Noise from the Engine Pulley?
1 Answers
Engine pulley squeaking may be due to the belt slipping on the generator, causing intense friction and vibration between the belt and the pulley, which produces a noise at a certain frequency. Below are the relevant explanations: Reasons for belt slipping: The main causes of belt slipping are belt looseness or aging. Factors that can lead to belt looseness include improper adjustment of the belt tensioner or insufficient tensioner spring force. In such cases, the tension of the belt tensioner should be adjusted first. If this does not resolve the issue, the tensioner should be replaced. Belt aging: Belt aging primarily refers to the belt gradually hardening and losing elasticity over prolonged use, resulting in reduced friction between the belt and the pulley. In this situation, the only solution is to replace the belt.
