Solution

1. Preparation

Gather necessary tools: socket set, torque wrench, belt tension gauge, and a flashlight.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Remove the Old Drive Belt

Disconnect Battery:
- Disconnect the negative terminal of the battery to prevent electrical issues.
Loosen Belt Tension:
- Use a socket and ratchet to rotate the tensioner pulley counterclockwise, relieving tension on the belt.
Remove Belt:
- Slide the belt off the pulleys, noting the routing path for reinstallation.

3. Inspect and Replace Components

Inspect Tensioner:
- Check the belt tensioner for proper spring action and replace if faulty.
Inspect Pulleys:
- Spin each pulley to check for smooth operation; replace any damaged or misaligned pulleys.
Install New Drive Belt:
- Route the new belt over the pulleys according to the routing diagram (usually located under the hood).
- Ensure the belt is seated properly on all pulleys.

4. Reapply Tension

Tighten Tensioner:
- Rotate the tensioner pulley again to apply tension to the new belt, ensuring it is tight and correctly aligned.
Recheck Alignment:
- Visually inspect the belt alignment on the pulleys to confirm correct installation.

5. Reconnect Battery

Reconnect the negative terminal of the battery.

6. Test the System

Start the vehicle and observe the belt operation for any unusual noises or misalignment.
