This should Help

Go to this link and you will find the diagram your lookiing for. Count the belt contact points(pully) and notice where they are. http://www.paulstravelpictures.com/GM-Pontiac-Grand-Prix-Serpentine-Belt-Replacement-Guide/GM-3800-II-Serpentine-Belt-Replacement-Guide-003.html

You probably have it fixed by now, but you should have a 3.8L V6 (no supercharger).
The belt routing should be the same as my Impala 3.8L.

I believe that the Bonneville's have a motor mount that needs to be unbolted to get the belt out. I had to go to a mechanic to get mine done.

If you don't see a diagram under your hood somewhere, just put it around the crank pulley, and go "ribs to ribs, flat to flat" , and work your way around.

these motors have two carrier pulleys and oone tensioner. lookinjg at the motor from the rightside of car the belt goes as follaws: crank pully to super charger from the left. the right side goes up to the lower carrier which will have the flat of the belt riding on it. from there the belt routes to the upper carrier
[ loop it over so the grooves ride
] and then under the tensioner any questions contact [email protected]
