Goin' to work this morning and I thought I threw my serpentine belt. Found out the Idler pulley broke in half, fell off and I lost my belt tension.
Just by chance I took the pulley off my wife's 01 Grand Prix to see if I could get it home. It worked, the inside bearing dimension was the same but it was a bit smaller on the outside of the pulley. it was enough to put tension back on the belt so I could drive it home.
My question is, has anyone found a substitute pulley to fit the 96 Disco 4.0 l engine?
I've check part sites and they want to sell the entire tensioner, not just the pulley. They run $170.00 to $250.00 for the entire unit.
Looking for the cheaper route.
If anything I could buy the Grand Prix pulley, it did work, but it had a smaller outside dimension.
Used parts are pretty hard to find around here.

 

I bought just the pully from AutoZone when my pully bearing went bad.
I think it was $24, but that was 2 years ago so i dont remember for sure.
www.autosportsunlimited.com and www.roverlandparts.com for used ones.
Take your old one (whats left) into NAPA and they will match up a new on for you.
