1. Preparation

Gather necessary tools and parts.
Tools Required:
- Ratchet and socket set
- Torque wrench
- Serpentine belt tool (optional)
- Safety goggles
- Gloves
Parts Required:
- New serpentine belt
Ensure the vehicle is parked on a level surface, and the engine is off and cool.

2. Remove the Old Serpentine Belt

Locate the serpentine belt tensioner: Identify the tensioner pulley on the engine.
Release tension: Use a ratchet or serpentine belt tool to rotate the tensioner counterclockwise. This will relieve tension on the belt.
Remove the belt: While holding the tensioner, slip the belt off the pulleys, starting with the tensioner pulley.
Inspect pulleys: Check all pulleys for wear or damage as you remove the belt.

3. Install the New Serpentine Belt

Route the new belt: Refer to the belt routing diagram typically found on a sticker under the hood. Ensure the belt is routed correctly around all pulleys.
Reapply tension: Rotate the tensioner counterclockwise again and slip the belt over the tensioner pulley while maintaining tension.
Check alignment: Ensure the belt is seated correctly in all grooves of the pulleys.

4. Final Checks

Inspect the installation: Double-check that the belt is properly aligned and secured on all pulleys.
Start the engine: Turn on the engine and listen for any unusual noises. Observe the belt’s operation to ensure smooth movement.
