Allright something so easy is turning into a pain. Anyways I got the belt tensioner pulley of my 97gtp. I went around looking to buy new one, and they all come w/ heater hose ports, and mounts differently than mine.
Mine is just a tensioner, and pulley that mounts on the e-torx stud. It has part # 24504322 on it. The part # with the heater hose ports comes up 02450818, for my car. Looks like i'll have to bring it to dealer?????

That's what I had to do.

We have 2 belts and 2 tensioners on our GTP's. The one with the heater ports is towards the firewall for the "normal" serpentine belt. The one towards the car's nose is for the supercharger drive belt.

Every place I went to did not have the S/C tensioner. I resorted to the dealer. I think you could get it from www.rockauto.com, but I was under time constraints.

$80.52 later, I ended up with part number: 12564506.
