    The diagram you gave also had the supercharger (I wish mine did) anyways, thanks. It worked great. Less than a 5 minute job!
    Many thanks!

    It looks just like the diagram except I do not have or need the 2nd belt because I do not have the supercharger.

How to put supertine belt on 2004 grand prix

Under the hood there will be a routing diagram for the serpentine belt. Use that as a guide for replacement routing. There is an automatic belt tensioner in the loop. Use an appropriate tool to release the tension on the old belt and remove it from the vehicle. Route the new belt as per the diagram and allow the automatic tensioner to re-tension the belt.

I need to replace the serpentine belt on my 2007 Grand Prix, but I cannot find a routing diagram anywhere. There is not one under the hood. The manual does not have a diagram either. Where can I find one?...

If you have the 3800 Series II or Series III engine, this should help you out.

If you dont have the supercharger, just disregard the belt routing with the S/C on it.
