I need a diagram of how to put the belt on my 1996 pontiac Bonniville SSE with super charge

Hi Cheryl! Look around the engine compartment, sometimes there's a diagram for the route of the belt. If not, head to your local library where they will probably have the Chilton's manual for your Bonni. If they don't try your local big box parts store to see if you can sneak a peek at the manual or ask a counter guys for help. These guys are usually very resourceful. Good luck!

a repair manual is cheaper than guessing.

Take pics with your smart phone. On all auto and just every project you do.
