Here are the best places to search for this diagram, once you know the engine:
* Online Repair Manuals: Websites like Chilton, Haynes, and AutoZone often have online repair manuals (some free, some subscription-based). Search for your specific year, model, *and engine size*. The manual will have a detailed belt diagram and routing information.
* Online Parts Stores: Sites like Advance Auto Parts, AutoZone, Napa Auto Parts, etc., allow you to select your vehicle's details (year, make, model, engine). Sometimes their diagrams are included in parts listings related to belts or pulleys.
* Chevrolet/GM Service Manuals (if you can find one): These are the most authoritative source, but they can be hard to find and often quite expensive. Used copies might be available on eBay or specialized automotive booksellers.
* Local Auto Parts Store: A knowledgeable parts counter person at your local auto parts store should be able to look up a diagram or print one for you if they have access to a parts catalog system with detailed diagrams. Again, having the engine size is crucial.
* Online Forums: Chevy Nova enthusiast forums (search for "1974 Chevy Nova forum" on Google) may have members who have created or shared diagrams. Someone with a similar car might be able to help.
Remember to always double-check the diagram against your own engine bay before attempting any belt work. There can be slight variations even within the same model year.
