My 2018 C coupe’s belt is squealing when accelerating
As the title says it, i have a belt slip issue. I think the belt tension is somehow not enough. I hvae 150.000km in the car. I changed the belt and the belt tensioner, but the squeaking, chirping noise is unbearable when I accelerate. I checked the pulleys too, they dont make any sounds, so it shouldn’t be the bearings. It’s driving me insane. Could it be that one of the pulleys is misaligned? If yes, how can I align them
Thank you for all the answers.
