What Causes the Belt to Squeak When Cold but Stop When Warm?
1 Answers
Cold belt squeaking that disappears when warm can be attributed to the following reasons: Loose Belt: Factors causing belt looseness include improper adjustment of the belt tensioner or insufficient tensioner spring force. Solution: Adjust the screw spacing between the belts. Belt Aging: Belt aging mainly refers to the gradual hardening and loss of elasticity over prolonged use, reducing friction between the belt and pulley. Solution: Repeatedly clean the belt with lubricant to restore tension. Excessively Worn Belt: An overly worn belt may slip and squeak, while excessive tightness increases resistance and causes premature wear on bearings of driven components like the alternator, water pump, and air conditioning. Solution: Replace with a new belt.
