1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool if it has been running.

Locate the belt tensioner: Use the appropriate socket to relieve tension on the belt.
Remove the belt: Carefully slide the belt off the pulleys, noting the routing path for reinstallation.

3. Inspect Components

Check the tensioner: If it is worn or does not hold tension, it should be replaced.
Inspect pulleys: Ensure all pulleys are free from debris and properly aligned. Replace any damaged pulleys.

4. Install New Belt

Route the new belt: Follow the routing diagram located in the engine bay. Make sure the belt is seated properly on all pulleys.
Reapply tension: Use the tensioner tool to apply tension to the belt and ensure it is securely in place.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and listen for any unusual noises. Check that the belt is tracking correctly and the tensioner is functioning.
