Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical issues.

Tools Required:

Socket set (including ratchet and extensions)
Torque wrench
Serpentine belt tool or breaker bar
Screwdrivers (flat and Phillips)

2. Remove the Old Serpentine Belt

Locate the serpentine belt routing diagram, usually found on a sticker under the hood.
Use a serpentine belt tool to relieve tension on the belt tensioner.
Carefully slide the belt off the pulleys, noting the routing for reinstallation.
Inspect the old belt and components for further damage.

3. Install the New Serpentine Belt

Position the new serpentine belt according to the routing diagram.
Start by placing the belt over the crankshaft pulley, then over other pulleys following the diagram.
Use the serpentine belt tool to relieve tension on the tensioner again, allowing you to slip the belt over the last pulley.
Ensure that the belt is properly seated in the grooves of all pulleys.

4. Final Checks

Double-check the belt routing against the diagram.
Reconnect the negative battery terminal.
Start the engine and visually inspect the belt operation.
