Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Serpentine belt tool or a suitable wrench
- Ratchet
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical issues while working.

2. Remove the Old Serpentine Belt

Locate the serpentine belt routing diagram, usually found on a sticker in the engine bay or in the owner's manual.
Use the serpentine belt tool to relieve tension on the tensioner pulley.
While holding the tensioner, slide the belt off the pulleys, starting with the tensioner and moving to the other components.
Remove the belt completely from the engine compartment, noting the routing for the new belt installation.

3. Inspect and Prepare Components

Inspect the tensioner and idler pulleys for any signs of wear or damage.
If necessary, replace the tensioner or idler pulleys based on the inspection findings.
Ensure that all pulleys are free of debris and in good condition.

4. Install the New Serpentine Belt

Refer to the routing diagram to guide the placement of the new belt.
Begin threading the new belt around the pulleys, starting from the crankshaft pulley and moving to the tensioner last.
Use the serpentine belt tool to pull the tensioner back again, allowing the belt to be positioned over the tensioner pulley.
Slowly release the tensioner to apply tension to the new belt.

5. Final Checks

Inspect the belt to ensure it is properly seated on all pulleys.
Reconnect the battery.
Start the engine and observe the belt operation for any abnormal noises or misalignment.
