What Causes the Belt Squeaking in Mercedes-Benz E-Class?
1 Answers
Mercedes-Benz belt squeaking reasons are as follows: Loose Belt: Factors causing belt looseness include improper adjustment of the belt tensioner or insufficient tensioner spring force. The solution is to adjust the screw spacing between the belts. Belt Aging: Belt aging mainly refers to the belt gradually hardening and losing elasticity during prolonged use, reducing friction with the pulley. The solution is to repeatedly scrub the belt with lubricating oil to restore tension. Excessively Worn Belt: An overly worn belt may slip and squeak, while an overly tight belt increases transmission resistance and causes premature wear of bearings in the generator, water pump, and air conditioning components. The solution is to replace the belt with a new one.
