* Online Repair Manuals: Sites like Chilton, Haynes, and AllDataDIY offer repair manuals (often subscription-based) with detailed diagrams and routing instructions. These are your best bet for accuracy.
* Your Vehicle's Owner's Manual: While unlikely to have a detailed diagram, your owner's manual *might* show a simplified illustration of the belt routing or refer you to a diagram in a separate section.
* Auto Parts Store Websites: Websites of major auto parts retailers (like AutoZone, Advance Auto Parts, Napa Auto Parts) often have online parts lookups. Entering your vehicle's details might reveal a diagram as part of the belt replacement instructions or within the parts catalog. However, the diagrams may be less detailed than a dedicated repair manual.
* Online Forums and Communities: Searching on forums dedicated to Buick Corsicas or General Motors vehicles (e.g., forums on sites like cargurus.com or dedicated Buick enthusiast forums) might yield someone who has already posted a picture or description of the belt routing.
* YouTube: Search YouTube for "1993 Buick Corsica 3.1L serpentine belt replacement." Many videos show the belt routing visually. However, always double-check against a more reliable source like a repair manual to ensure accuracy.
Important Note: When replacing a serpentine belt, always refer to a reliable diagram and carefully match the belt routing to prevent damage to the engine. Incorrect routing can lead to premature belt failure or damage to components.
