Replacing the Serpentine Belt

To replace the serpentine belt on a 2015 Ford Explorer, follow these steps:

1. Gather Tools: You will need a ratchet, a serpentine belt tool or a combination wrench, and possibly a long screwdriver for assistance.

2. Release Tension: Locate the tensioner pulley on the passenger side of the engine. Use your ratchet or serpentine belt tool to rotate the tensioner clockwise to relieve tension on the belt.

3. Remove Old Belt: With the tension released, carefully slip the old belt off starting from the alternator or AC compressor.

4. Install New Belt: Begin by routing the new serpentine belt around the crankshaft pulley. Then work it around the AC compressor and under the tensioner pulley.

5. Finish Routing: Pull up on the tensioner again and loop the belt over the alternator last. Ensure that all parts of the belt are seated properly in their respective grooves.

6. Inspect Installation: Before releasing tension, double-check that all sections of the belt are correctly aligned and seated to avoid slippage or damage when you start your engine.

7. Test Run: Start your vehicle and observe for any unusual noises or misalignments in the belt path.
