* Repair Manuals: Repair manuals like those from Haynes or Chilton will have detailed diagrams and instructions for replacing the serpentine belt. These are available online and at auto parts stores.
* Online 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 year, make, and model. You'll usually need to enter your vehicle's information to get the correct diagram.
* Google Images: A Google image search for "1999 Chevy Malibu serpentine belt diagram" might yield some results, but be cautious, as the accuracy isn't guaranteed. Always double-check against a more reliable source.
