Solution

1. Preparation

Gather tools and parts needed for the replacement.
Disconnect the negative battery terminal to ensure safety.

2. Remove the Serpentine Belt

Locate the serpentine belt routing diagram (usually found on a sticker under the hood).
Use a wrench or ratchet to relieve tension on the serpentine belt tensioner.
Carefully slide the belt off the pulleys, taking note of its routing.

3. Inspect Components

Examine the pulleys and tensioner for wear or damage.
Rotate each pulley manually to ensure they spin freely without resistance.

4. Install New Serpentine Belt

Position the new serpentine belt according to the routing diagram.
Ensure the belt is seated properly on all pulleys and is not twisted.
Use the wrench to apply tension to the tensioner and slide the belt onto the last pulley.

5. Final Checks

Reconnect the negative battery terminal.
Start the engine and observe the belt in motion to ensure it is functioning correctly without noise or slippage.
