Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety.
Raise the vehicle if necessary for better access.

2. Remove the Old Serpentine Belt

Tools Required: Socket set, belt removal tool (if needed)
Locate the tensioner pulley and use a socket to relieve tension on the belt.
Slide the belt off the tensioner and then off the other pulleys, taking note of its routing for reinstallation.

3. Inspect and Replace Components

Inspect the tensioner pulley:
- If it's worn or not functioning properly, remove it by unbolting it from its mounting bracket using the socket set.
- Replace with a new tensioner if necessary.
Check all other pulleys for damage; replace any that are worn or damaged.

4. Install the New Serpentine Belt

Place the new serpentine belt according to the routing diagram typically found on the engine cover.
Start by placing the belt around the crankshaft pulley, then around the other pulleys, finally routing it over the tensioner pulley.
Use the socket to rotate the tensioner again and slide the belt into place.

5. Reassemble and Test

Reconnect the negative battery terminal.
Start the engine and observe the belt's operation. Listen for any abnormal noises and check for proper alignment on all pulleys.
