So i replaced my timing belt, and every other belt about 1000 miles ago. I opened my hood today, and it looks like my serpentine belt is off track and getting eaten up on one edge..... but why?? I released the tensioner a bit and tried to realign the belt around the alternator, and tensioner and stuff, then I started the car, and it went right back into the place it was before. Here are some pictures, any and all help is greatly appreciated!!

These are when I tried to align it, and yeah, that part is frayed pretty bad....

This is only after 1000 miles.... I have to get this fixed soon!

Thank you!

This happen to me once.. there was a bolt at the bottom of the alternator backing out and hitting the belt tightened it and never had a prob since.

Holy chit, that's nasty. Try tracing the belt's path see it's rubbing against anything. Make sure that the tensioner bolts are tighten properly and not crooked.

I just checked all the bolts in that area and they are super tight. But i just realized I have a little bit of side to side play in my tensioner when I pull it back (releasing the tension on the belt). Maybe thats it? Or maybe all the tensioners have a little? I'm not really sure. Right now, Im trying to release tension, position, crank engine a tiny bit, release tension, position, and so on till I make a full revolution. Not sure if its working though. It almost seems like its the crankshaft pulley, but the AC belt is perfectly fine...

New tensioners shouldn't have ANY play in them. I remember examining my new one and it was solid. That could be the culprit. Is it a new or old tensioner that you have?

I believe its the stock original tensioner. Since in was for the serpentine belt, I just figured I'd reuse it. I'm not sure what you mean by new or old, like new or old style tensioner, or physically newer or old? Its not a physically new one, no.

Accessory belt tensioner is different from the timing belt tensioner. If there is play in it and it is bolted down all the way, you need a replacement. Should be 3 bolts on it. Recheck they are torqued down correctly.

I figured since I drove 1500 miles on that belt, it would last another 500 at least... never have I been so wrong. Its been about 20 miles since I posted those original pictures.

I present to you whats left of my belt:

You need a new belt tensioner as mentioned gl.

These tensioners have a relatively big price difference... would it be okay to get the cheaper on, or should I not risk it? I guess Im asking: Which one would you buy?

I'd get the cheaper one, its fairly easy to change if it messes up.

Spend the money for the better and do it once.
