Have you actually taken the auto tensioner off mate? Reason i ask is i had the same problem a while ago and upon taking the tensioner off i noticed the bearing was shot, spring part was fine. Just needed a bit of WD40 and a working to be nice and smooth and tight again.Hi im looking for a alternater/power steering pump tensioner for an evo 4 as mine squeaks on a cold start. its the self adjusting one. if any one has a goog working non squeaking one then please contact me as im looking to buy.
