Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Worn Components

Belts and Hoses:
- Remove any engine cover if necessary.
- Visually inspect belts for cracks or wear; replace if damaged.
