Solution

1. Preparation

Gather tools and parts needed.
Disconnect the negative battery terminal to prevent electrical shock.
Ensure the engine is cool before starting work.

2. Remove the Old Belt

Tools Required: Socket set, ratchet, belt removal tool (if necessary).
Locate the belt routing diagram (usually found on the radiator support or engine cover).
Use the socket set to loosen the tensioner pulley. Rotate it clockwise to relieve tension on the belt.
Slide the belt off the pulleys following the routing diagram.

3. Inspect and Replace Components

Tools Required: Visual inspection tools (flashlight).
Check the condition of the pulleys and tensioner. Replace any damaged components.
If the tensioner is faulty, remove it using the socket set and replace it with a new one, ensuring it is securely fastened.

4. Install the New Belt

Parts Required: New serpentine belt.
Refer to the belt routing diagram to correctly route the new belt around the pulleys.
Rotate the tensioner pulley again to provide slack and slide the new belt onto the pulleys.
Release the tensioner to apply tension to the new belt.

5. Final Checks

Reconnect the negative battery terminal.
Start the engine and observe the belt operation for any unusual noises or misalignment.
