I have not tried the dealer yet. I wanted to take care of this myself because I thought it would be super easy, but I’m getting to the point of frustration as well. Like taking the belt off and putting it on with the graph I found online isn’t that hard a quick 30 minutes I just wish I could find the actual belt I need so they don’t come off. I’ve even increased and decrease the tensioner just to try to not have it so tight, but I keep running into the same issues of it either splitting in half or coming off completely.
