Solution

1. Preparation

Tools Required:
- Socket set (including 10mm and 13mm sockets)
- Ratchet and extension
- Torque wrench
- Serpentine belt tool or long-handled wrench
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove the Engine Cover

Remove any screws or clips holding the engine cover in place.
Lift the cover off and set it aside.

3. Relieve Tension on the Serpentine Belt

Locate the serpentine belt tensioner (typically on the side of the engine).
Use the serpentine belt tool or a wrench to rotate the tensioner counterclockwise, relieving tension on the belt.
Slip the belt off the pulleys while maintaining tension on the tensioner.

4. Inspect and Replace the Belt

Compare the old serpentine belt with the new one to ensure it is the correct length and width.
Install the new serpentine belt by routing it according to the belt routing diagram often found on a label near the engine compartment.
Ensure the belt is properly seated on all pulleys without twisting.

5. Reapply Tension

Rotate the tensioner again with the tool or wrench to allow the belt to slip onto the tensioner pulley.
Release the tensioner slowly, allowing it to apply tension to the new belt.

6. Reinstall Engine Cover

Place the engine cover back into position and secure it with screws or clips removed earlier.

7. Reconnect Battery

Reconnect the negative battery terminal.
