* Repair Manuals: A Haynes or Chilton repair manual specifically for a 1991 Chevrolet Cavalier will have a detailed diagram, often with clear labeling of each component the belt interacts with. These are readily available online and at auto parts stores.
* Online Parts Websites: Websites like AutoZone, Advance Auto Parts, or Napa Auto Parts often have diagrams available when you select your vehicle's year, make, and model. Search for "serpentine belt diagram" or "belt routing diagram" after selecting your car. They may be integrated into their parts ordering system.
* Online Forums: Search relevant automotive forums (like those specific to GM cars or the Cavalier) for "1991 Cavalier 2.2 serpentine belt diagram." Someone may have posted a picture or scan.
* YouTube: Search YouTube for "1991 Chevy Cavalier 2.2 serpentine belt replacement." While not always a dedicated diagram, many replacement videos show the belt routing clearly as they remove and replace the belt.
Important Note: Always double-check the diagram against your own engine bay. Diagrams can sometimes vary slightly depending on specific options or engine variations. Using a diagram from a different year or model Cavalier could lead to incorrect routing.
