To find the correct belt size, you have several options:
1. Measure: This is the most reliable method. Remove the AC compressor and carefully measure the length of the belt path using a flexible tape measure. Be sure to follow the belt's path around all pulleys *precisely*. Then, take this measurement to an auto parts store and they can help you find the closest matching belt.
2. Consult a Parts Store with the Vehicle: Visit an auto parts store (like AutoZone, Advance Auto Parts, or NAPA) with your truck's VIN. Explain that you've removed the AC compressor and need a serpentine belt for that configuration. They may have resources to help determine the correct size, or they might be able to measure based on your truck's year, make, model, and engine.
3. Online Resources (Use with Caution): Some online forums or websites *might* offer belt sizes for AC delete setups. However, this information should be treated with caution. Incorrect belt sizing could damage your engine. Always double-check with a professional if relying on online information.
Important Considerations:
* Tensioner: Removing the AC compressor might affect belt tension. You may need to adjust the tensioner pulley to ensure proper belt tension. Improper tension can lead to belt slippage or premature wear.
* Routing: Make sure you understand the correct routing of the belt around the remaining pulleys. An incorrect routing can also cause problems.
* Professional Assistance: If you are not comfortable with this procedure, it's best to take your vehicle to a mechanic. Incorrect belt installation can cause severe engine damage.
In short, measuring the belt path yourself and having it matched at a parts store is the safest and most reliable way to get the correct belt size after removing your AC compressor.
