Solution

1. Preparation

Tools Required:
- Socket set
- Ratchet and extension
- Torque wrench
- Belt tensioner tool (if needed)
Ensure the vehicle is parked on a level surface and the engine is off and cool.
Disconnect the negative battery cable to prevent electrical shorts.

2. Access the Serpentine Belt

Remove any engine covers if applicable using the socket set.
Locate the serpentine belt routing diagram, usually found on a sticker in the engine bay or in the owner's manual.

3. Release Tension on the Serpentine Belt

Use a belt tensioner tool or a ratchet with the appropriate socket to rotate the tensioner counterclockwise, relieving tension on the belt.
Carefully slide the belt off any driven pulleys while maintaining tension on the tensioner.

4. Remove the Old Serpentine Belt

Once the belt is loose, carefully remove it from the remaining pulleys, noting the routing for installation of the new belt.
Inspect all pulleys for damage or wear, replacing any that are found to be defective.

5. Install the New Serpentine Belt

Place the new serpentine belt over the pulleys according to the routing diagram. Ensure that the belt is seated properly in all grooves.
Rotate the tensioner again counterclockwise and slip the belt onto the tensioner pulley last.
Release the tensioner slowly to apply tension to the new belt.

6. Final Checks

Reinstall any engine covers that were removed.
Reconnect the negative battery cable.
Start the engine and observe the belt for proper alignment and tension, ensuring there are no unusual noises.
