Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Serpentine belt tool or a long-handled ratchet
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery cable to prevent electrical shorts.

2. Remove the Old Serpentine Belt

Locate the serpentine belt tensioner, which is typically located on the front of the engine.
Use the serpentine belt tool or a ratchet to rotate the tensioner counterclockwise to relieve tension on the belt.
While holding the tensioner in place, carefully slide the belt off the pulleys. Note the routing of the belt for reinstallation.
Slowly release the tensioner back to its original position.

3. Install the New Serpentine Belt

Refer to the belt routing diagram, which is often found on a sticker under the hood or in the owner's manual.
Begin threading the new serpentine belt around the pulleys, starting from the crankshaft pulley and following the routing path.
Ensure the belt is seated properly in all grooves of the pulleys.
Again, use the serpentine belt tool or ratchet to rotate the tensioner counterclockwise and slide the belt over the tensioner pulley.
Release the tensioner, allowing it to apply tension to the new belt.

4. Final Checks

Inspect the belt to ensure it is aligned correctly on all pulleys.
Reconnect the negative battery cable.
Start the engine and observe for any abnormal noises or signs of misalignment.
