My Ride: 2003 BMW 325ci
A/C tensioner pulley

I was changing my belts on my 2003 325ci and I noticed that my A/C tensioner pully needed replacing. when i went to the the parts store the pully they gave me was completely different. After a internet search all i could find were those pullues. Why are they so different? I have a sprung tensioner not a hydrolic tensioner . the pulley on the tensioner for the other belt is the same style as the one on the A/C.

went to advanced auto yesterday and bought new ac belt and tensioners. It's PN89133 $33.16. Belt is PN5040340 $20.99
Maybe think about replacing Idler pulley and your other tensioner as well. I did all of this yesterday for 160.30 You can view my parts list etc. on the general forum page.
