have a 2002 Ford Escort 2.0L My problem is that the belt tensioner keeps bo uncing back slightly making a not too loud noise, but noticeable clatter. Its as if the belt tensioner isnt tensioning enough or the force of the belt is pushing it back. I replaced the tensioner and belt and still the same p roblem. Anyone have any ideas whats wrong here? AllData manual shows that i ts a simple procedure to change belt and that belt tensioner puts the corre ct tension no matter what. Im totally lost here. Would appreciate any help or ideas as what could the problem be. E.T.
