    I'm having a problem with my belt tensioner I think. I noticed that the tensioner was pushing the belt into the power steering pully and that the belt was coming off the tensioner slightly forward of the PS pulley. When it came off the alternator pulley it lined up properly with the PS pulley. It frayed the belt edge. I took off the tensioner and noticed that it was past the limit indicator. So I guess it's junk! I have a 1994 parts car, the tensioner seemed to be farther away from the PS pulley. I took it off but the spring is somewhat stuck so that's no good either. But it had a smaller pulley on it than my 1993. The pulley on the 1993 is original, I don't know about the 1994. Besides these differences in pulley diameter the cars are identical. Parts car is a Tracer but a 4 door sedan. Anybody have any input into why one pulley is different? From the factory perhaps?

    Sounds like all you need is a slightly shorter serpentine belt.

    Probably the kid at Autozone sold me the wrong belt. I'll try Napa or O'reilly maybe I'll get the right one! I still need a tensioner though! I'd buy from Rockauto but can't wait.

    You were right millball, I just needed a shorter belt. Went to Pepboys and said if it doesn't fit I'm returning it. The box looks like they had it in back for 20 years! Dayco Polyrib #5060535. It's all fixed now!

    The factory pulley has a larger diameter. If you have replaced the pulley, you have a smaller one and need a belt that is 1/4" shorter.

    the belt usually comes pretty close to the ps pulley, but shouldn't be touching.

    The O.P. clearly has a too-long belt, and I will not beat on that dead horse.

    However, I will add this about pulley diameters. All other accessories being equal (i.e. two cars both having p/s and a/c), there was a change in alternator pulley sizes (but not in the alternators themselves) between '93 and '94. This is why most catalogs will show a 53.5" belt for a '93 and a 53" belt for a '94 . Over time, heaven only knows what alternator might be on a 2nd Gen, so a belt length complaint might simply be an alternator switch along the way, and not mysterious voodoo at work.

    I have encountered the same issue, having one each of 91LX, 92LX, 93LX, and 94LXs. I just get the belt that is longer or shorter as necessary. Once when buying a rebuilt alt from "arlington armature", a rebuilder, the one they handed me had a larger pulley than the 'core' I had given them. I asked if they could swap the pulleys, which they cheerfully did.
    I also had one Escort having the wrong diameter pulley for the idler. The idler and tensioner pulleys arent the same size. I think one of them is 90mm, while the other is 100mm, but I forget which is which.

    just noticed today on my girlfriends escort it had the longer belt and the tensioner pully was wearing a groove on the power steering pulley. I put on the shorter 94 belt and it fixed the problem.
