I want to replace the belt on my ML as it is past due for replacement. After checking the belt tensioner I don't really see a bolt or nut that would loosen/tighten the tension on the pulley. If anyone out there has replaced the belt, I could use some pointers if you have any. I think it might be the bolt/nut in the center of the pulley, but I'm not certain. Thanks in advance for your help!
