Solution

1. Preparation

Tools Required: Socket set, belt tension gauge, OBD-II scanner, flashlight
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove the Accessory Belt

Use a socket wrench to relieve tension on the belt tensioner.
Carefully slide the belt off the tensioner pulley.
Remove the belt from all other pulleys, taking note of the routing.
Inspect the old belt for signs of wear and any damage.

3. Inspect and Replace the Tensioner (if necessary)

Remove the tensioner assembly by loosening the mounting bolts.
Compare the old tensioner with the new one to ensure proper fit.
Install the new tensioner by tightening the bolts to the manufacturer's torque specifications (typically around 15-20 Nm).
Ensure the tensioner moves freely and is properly aligned.

4. Install New Accessory Belt

Refer to the vehicle's service manual for the correct belt routing diagram.
Place the new belt over all pulleys except the tensioner.
Use the socket wrench to again relieve tension on the tensioner.
Slip the belt over the tensioner pulley and release the tensioner to secure the belt.
Double-check the belt routing and tension.

5. Reconnect Battery and Verify Function

Reconnect the negative battery terminal.
Start the engine and observe the belt operation for smoothness and proper alignment.
Listen for any unusual noises.
