* Your Owner's Manual: The most likely place to start. Check the diagrams section, often towards the back.
* Online Repair Manuals: Sites like Chilton.com or AllDataDIY.com (subscription required) offer detailed diagrams and repair information. These are usually very accurate.
* Dodge Repair Manuals (physical): You can find physical repair manuals at auto parts stores or online retailers. These are comprehensive but can be expensive.
* Auto Parts Store Websites: Websites of major auto parts stores (e.g., AutoZone, Advance Auto Parts, NAPA Auto Parts) often have diagrams associated with the serpentine belt kits they sell. Search for your specific vehicle's year, make, model, and engine. Look for diagrams on the product pages or in their online catalog.
* YouTube: Searching YouTube for "2005 Dodge 3500 5.9 Cummins serpentine belt diagram" might yield a helpful video showing the routing. However, be sure to verify the information with a more reliable source.
Important Note: When replacing a serpentine belt, always consult a reliable diagram to ensure correct routing. Incorrect routing can damage the belt, alternator, power steering pump, and other components.
