The 1997-2003 Pontiac Grand Prix GTP is equipped with an Eaton M90 supercharger on top of the GM 3800 Series II 3.8L V6 engine. I recently replaced both the Serpentine (accessory) belt and the supercharger belts. For the complete guide to replacing the supercharger belt, click on the text link or thumbnail image below.
