Installation Guide

Follow these general steps to replace your serpentine belt. Always refer to your engine's service manual for detailed instructions specific to your model.

1. Safety First: Ensure the engine is cool and disconnect the battery's negative terminal.
2. Locate Tensioner: Identify the automatic belt tensioner pulley.
3. Release Tension: Use a properly sized wrench or breaker bar on the tensioner to rotate it and release the tension from the belt.
4. Remove Old Belt: Carefully slide the old belt off the pulleys. It's helpful to sketch or photograph the belt's routing path beforehand.
5. Inspect Pulleys: Before installing the new belt, spin each pulley by hand to check for wobble, noise, or resistance, which could indicate a failing component.
6. Install New Belt: Route the new belt according to your diagram or manual, ensuring it is correctly seated in the grooves of each pulley.
7. Apply Tension: Slowly release the tensioner, allowing it to apply the correct amount of tension to the new belt.
8. Final Check: Double-check that the belt is properly aligned on all pulleys and that all tools have been removed from the engine bay.
9. Test: Reconnect the battery, start the engine, and listen for any unusual noises. Let it run for a few minutes to ensure proper operation.
