5.7 vortec serpentine belt

[jt1500]

hey guys i just changed my serpentine belt for piece of mind, and now it seems to be squealing and slips a fair bit off and on. is this normal or does it just need to self adjust?

I use to have that Issue with mine on my 97. I replaced it with a Gates brand belt and I haven't had that issue again. I know the Gates it twice as much, but it is worth the money.

Tensioner spring could be weak.. or the belt could be too long, or a combination of both.

ran some part numbers on the dayco site, turns out my old belt is 1.56" shorter than my new belt. hence why its slipping. ill have to try and exchange it

so for now im running my old belt with no noises

Awesome! It could be the case of someone bought a few belts, and slipped the wrong sleeve on to return it... having worked in a parts store for 5 years a lifetime ago, I have seen it all!

Worst offenders were U-joints. People would buy the internal and external clip ones, and bring back the ones they didn't need, albeit swapped all around, because they don't care.

I've had that happen a few times with mower belts get the right part number but wrong belt go back and get another one with the same part number and it's correct
