This video I made shows you how to change your supercharger belt and serpentine belt.

Additionally, it covers the installation of upgraded 3 piece idler pulleys, and the supercharger tensioner pulley.


Tools required:

17mm box wrench

17mm deep socket and 3/8" drive ratchet.

4mm allen key, or anything simile sized.

t40 and t50 Torx bits, on 3/8" drive ($10 from home depot, **only needed to change tensioner or idler pullies)




Hope this helps, any questions just ask here.

Glad to help. Thanks to shardul for getting me those pulleys at a killer price. I think he has more sets available if anyone needs them.

Also, shouldnt youtube videos show up as embedded? Having to click a link is kind of archaic in this day and age lol. Vbulletin Forums should be auto-embedding.

Yeah, it's no biggie. If I hadn't been making a video, the whole thing would only take 30mins

One thing I'd like to mention is that you should clean the inside of the torx bolt heads.. It can get grimey in there and make for a poor fit with the torx bits. The last thing you want is to strip the bolts when trying to remove them..

Sorry to bring this back from the dead but what does the idler pulley bolt thread into? I believe mine is stripped. I haven't removed it yet so I'm not sure if it's the bolt or what it threads into. Just trying to gauge how screwed I am if its not the bolt.
