Solution

1. Preparation

Tools Required: Socket set, ratchet, torque wrench, serpentine belt tool (or long-handled wrench), safety glasses.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool completely before starting the repair.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove the Old Serpentine Belt

Locate the serpentine belt tensioner, which is usually positioned near the front of the engine.
Use the serpentine belt tool to relieve tension from the tensioner by rotating it counterclockwise.
Carefully slide the belt off the pulleys while maintaining tension on the tool.
Once the belt is free, slowly release the tensioner back to its original position.

3. Install the New Serpentine Belt

Refer to the belt routing diagram, often located near the engine bay or in the owner’s manual, to ensure the correct installation path.
Start routing the new belt around the pulleys, ensuring it is seated properly in all grooves.
Use the serpentine belt tool to again rotate the tensioner counterclockwise and slip the belt over the last pulley.
Carefully release the tensioner to apply tension to the new belt, confirming it is correctly seated.

4. Final Checks

Inspect the belt to ensure it is properly aligned and fits snugly on all pulleys.
Reconnect the negative battery terminal.
Start the engine and observe the belt in operation for any misalignment or abnormal sounds.
