Tensioner Pulley parts

My tension pulley bearing is starting to squeal. The auto parts store replacement is at least a 1/4" thinner and the belt has one rib not on the pulley. Apparently the pulley on my truck is the original from factory. Anyone here run into this issue replacing the tensioner pulley. Any help would be appreciated.

When I replaced mine 6 years ago I just ordered one from Rock Auto, Installed it and have had zero issues.

You can also press out the bearing and reinstall a new bearing in the tensioner if you are handy enough

The original is the best one.
I recommend swapping out the berring.
It is fairly easy to do.

Replacing the bearing is not a bad job at all. Shop around for a good US made bearing.

You bought the entire tensioner. I’m only looking for the pulley. So far all I’ve seen a lot thinner than mine.

If you want just the pulley then you can use ACDELCO 1520676

I'm going to post pictures of the difference in size with my original pulley and the ACDelco that i purchased also a picture of the purchased pulley with the belt installed. The serpentine belt rides on the outer edge of the new pulley.

I recommend replacing the tensioner and pulley. The tensioners go bad and they can cause a lot of damage when they do. My tensioner broke the pulley off of my AC compressor before I replaced it with a gates tensioner. Works great now.
