Hi all.My 96 Sprinter 312's fanbelt sounds like a bag of nails at tickover.I've looked at the belt and its slack on its longest run even after being replaced.The current theory is thats its the tensioner damper.Has anybody any thoughts cos its driving me up the wall.And does anybody know a simple way to remove the bottom bolt on the tensioner because theres a great big pulley in the way ! Thanks for reading this.
