Hi all, as part of getting my new(to me) SLK 200 up to the condition that I want it I intend to replace the ribbed drive belts, Aux drive belt and supercharger belt. I've performed a few searches and cant find a proccedure for this, I'm mainly concerned about the belt tensioners and how to relieve tension on the belts before removal. Has anyone replaced the belts that can give me a few tips? cheers. Mark.
