Solution

1. Preparation

Gather Tools: Belt tension gauge, flashlight, socket set, ratchet, and safety gloves.
Safety Warning: Ensure the engine is cool before starting work. Disconnect the battery to prevent accidental starts.

2. Inspect Belts

Visual Inspection: Open the hood and visually inspect the belts for any signs of wear, cracks, or glazing.
Check Alignment: Ensure that the belts are properly aligned on their pulleys.

3. Check Belt Tension

Using Tension Gauge:
- Attach the belt tension gauge to the belt and follow the manufacturer's specifications for proper tension.
- If the tension is below the recommended level, proceed to adjust or replace the belt.

4. Adjust or Replace Belts

Adjusting Tension:
- Locate the tensioner pulley. Use a socket to rotate the tensioner and relieve tension on the belt.
- Adjust the tension according to the specifications and release the tensioner to apply the correct tension on the belt.
Replacing Belts (if necessary):
- If the belt is worn or damaged, remove it by loosening the tensioner and sliding the belt off the pulleys.
- Install the new belt by routing it around the pulleys as per the belt routing diagram, ensuring it is seated correctly.
- Reapply tension using the tensioner.
