* Repair Manual: A Haynes or Chilton repair manual specifically for that year and model Cadillac will have a diagram showing the correct serpentine belt routing. These are available at most auto parts stores and online retailers. This is the most reliable method.
* Online Forums: Websites and forums dedicated to Cadillac or Northstar engines (like Cadillac Forums or similar) often have members who have dealt with this. Searching for "1996 Cadillac Seville STS serpentine belt diagram" or a similar phrase may yield helpful results, including user-submitted photos. Be cautious, however, as the accuracy of user-submitted information can vary.
* Online Parts Stores: Some online auto parts stores (like AutoZone, Advance Auto Parts, etc.) allow you to look up your vehicle by year, make, and model. While they may not have a dedicated diagram, the parts diagrams for the belt and associated pulleys might help you visualize the routing.
* Your Local Mechanic: Your local mechanic or auto parts store employee can likely provide assistance or point you in the right direction. They may have access to a repair manual or other resources.
Important Note: When replacing the serpentine belt, it's crucial to get the routing correct. Incorrect routing can lead to premature belt wear, pulley damage, and even engine damage. If you are unsure about the routing after consulting these resources, it is best to seek professional assistance from a qualified mechanic.
