1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety.
Raise the vehicle with a jack and secure it with jack stands if needed.

2. Remove the Existing Belt

Locate the belt routing diagram, typically found on the engine bay.
Use a socket or wrench to relieve tension on the belt tensioner and remove the belt from the pulleys.
Inspect the belt for any visible damage and note the routing for reinstallation.

3. Inspect and Replace Components

Inspect Pulleys:
- Check each pulley for smooth operation and wear. Replace any damaged pulleys.
Check Tensioner:
- If the tensioner is not holding tension properly, remove it using the appropriate socket size and replace it with a new one.

4. Install New Belt

Route the new belt according to the belt routing diagram.
Ensure the belt is properly seated on all pulleys.
Reapply tension using the tensioner and make sure it holds the belt securely.

5. Final Checks

Reconnect the battery and start the engine.
Listen for any unusual noises and check for proper belt operation.
Verify that all accessories are functioning correctly.
