2006 S500 AMG Wifes Rig Hillbilly Girl 02 ML320
Looks like I may have sold My 300 E! But I have this very bad squealing from the belt. I want the car right when the fella picks it up so I bought a new fan belt and took it down to my local small repair shop to have installed. He called me and said the tensioner was bad he said he could not tighten belt but also admitted he had never seen one "quite like it"! Could someone here explain how the adjuster works ? Is this spring or mech tension?? New tensioner from stealer is $175 so I want to be sure he is doing it right before I blow $175 clams !
