My belt tensioner arm is constantly flapping back and forth. The pulley seems fine, so I tried to replace my old tensioner with a tensioner from the dealer- and it didn't line up properly. The hole where the arm attaches to the pulley is offset (relative to the old tensioner) so that when I install it, I can't pull the arm back enough to get the belt on. When I install it, the pulley is resting on the alternator pulley (much further back than where the old one sat).
When I bought the part, I gave the dealer the part # on the old one, and he said that they changed the # slightly.
Anyone have the part #'s for both a '93 and '97 AAZ accessory belt tensioner? Are they the same?
