* Consult your owner's manual: This is the most reliable source. The manual should have a diagram showing the correct routing of the belt around all the pulleys.
* Look for a diagram under the hood: Some vehicles have a diagram stamped or stickered on the engine cover or underhood components showing the belt routing. It might be small and difficult to see, but it's worth checking.
* Use an online parts catalog: Websites like AutoZone, Advance Auto Parts, Napa Auto Parts, etc., allow you to search for your vehicle's year, make, and model. Once you've selected your vehicle, you should be able to find diagrams showing the serpentine belt routing (often found with parts relating to the belt). Be aware that different websites might have varying levels of detail or clarity.
* Use a repair manual specific to your vehicle: A Haynes or Chilton repair manual will contain detailed diagrams and instructions for replacing the serpentine belt, including the correct routing.
* Search online image databases: A Google Image search of "[your car year, make, and model] serpentine belt diagram" might yield useful results. However, be cautious and verify the information with one of the more reliable methods mentioned above. Incorrect information can lead to damage.
* Consult a mechanic: If you're unsure about the routing, taking your car to a mechanic is the safest option. They'll be able to quickly determine the correct routing and replace the belt if needed.
It's crucial to get the serpentine belt routing correct. Incorrect routing can cause the belt to slip, break, or damage the components it drives (alternator, power steering pump, water pump, etc.).
