Chewed up new serpentine belt?????

**cpw006** · 04-11-2010, 11:08 AM

I replaced my alternator the other day and put on a new Dayco(cheap belt friend had laying around) serpentine belt on it that I broke last night. I only had about 30 miles or so on the belt. It did not break it in half but shredded it along the length of the belt, kind of like it just unraveled. Today I bought a Goodyear Gatorback belt and put it on. I was looking at how it was riding on all the pullies and it seemed to be fine except for the small pulley down left from the power steering pulley. Its riding more to the front on this pulley, but is still on the pulley. Its not hanging off of this pulley any or anything, but now I am nervous that its not riding where it should be. My alternator and everything is seated into the right spot and snug to the block. Has anyone else had this problem and what was the reason. My tensioner pulley seems pretty tight. Could it have been the Dayco belt and do I need to worry about my Gatorback belt splitting like this.

Thanks for the help and sorry to ramble.

Drive it around and pull over and take a look at the belt. Chances are the belt you got from your buddy was already on its last leg and finaly let go. Did the new alt come with a pulley? If not did you seat the pulley on all the way? Post up pics of the belt on the idler pulley and we can tell ya if its riding right or not..

Edge shredding can also happens if you install the belt one groove off on any of the pulleys

Yes my new alt came with a pulley, I just drove about 40 miles or so and I got on hard a couple times and checked when I got home and the belt looks normal. Its seated in the center of all the pulley's so I am hoping I am safe. I am still going to drive around with a spare belt in the back for a while just in case. Thanks for the input.
