I checked the belt routing with the actual cars manual. It should be correct.
The belt is a MB belt, it should be the correct length and size.
I have changed th belt before on a few diff 190e cars. The tensioner is loose. The tensioner will move from side to side, back and forth.
What I cant get to happen is the belt to go on over all the pulleys. I dont know why. If the tensioner rubber is bad with that keep the adjuster nut from tightening? I put the belt on the way i thought was correct and it was way too loose and i could not get the tensioner to tighten up to take ouut the slack. I then checked the manual and saw they had a different routing for the belt. I rerouted the belt and the belt is not long enough to go on the pulleys in the route shown in the manual. I am stumped.
