Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working.

2. Inspect and Replace Serpentine Belt

Sub-steps:
- Locate the serpentine belt tensioner and use a wrench to relieve tension on the belt.
- Remove the serpentine belt from the pulleys.
- Inspect the belt for any signs of wear or damage.
- If worn, replace with a new serpentine belt (ensure it matches OEM specifications).
- Reinstall the new belt, ensuring it is properly aligned on all pulleys and under tension.

3. Check and Replace Tensioner or Pulleys (if needed)

Sub-steps:
- Inspect the tensioner for proper operation; it should maintain consistent tension on the belt.
- If the tensioner is faulty, remove it using a socket set and replace it with a new unit.
- Inspect all pulleys for damage or wear; replace any that are not spinning freely or are damaged.

4. Inspect Engine Mounts

Sub-steps:
- Locate engine mounts and visually inspect for cracks or signs of wear.
- If damaged, unbolt the engine mounts using the appropriate socket size and replace them with new mounts.
- Torque the new mounts to manufacturer specifications (check the service manual for specific values).
