* Your Owner's Manual: The best place to start. It should have a diagram, or at least a routing description.
* Online Repair Manuals: Sites like ChiltonDIY, AllDataDIY (subscription required), and Haynes offer online repair manuals with diagrams. These are often clearer and more detailed than what's in the owner's manual. Search specifically for "1997 Pontiac Grand Am 4-cylinder serpentine belt diagram."
* Automotive Parts Websites: Websites like AutoZone, Advance Auto Parts, and Napa Auto Parts often have diagrams available when you search for the serpentine belt for your specific vehicle. You usually need to enter your vehicle's year, make, model, and engine. Look for a section on diagrams or installation instructions.
* YouTube: Search YouTube for "1997 Pontiac Grand Am serpentine belt replacement." Many videos show the belt routing visually, which can be very helpful.
Important Note: When replacing a serpentine belt, it's crucial to follow the correct routing. Incorrect routing can damage the belt and other components of your engine. If you're unsure, it's best to consult a professional mechanic.
