Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Worn Components

Belts and Hoses Inspection:
- Visually inspect the serpentine belt for cracks, fraying, or glazing.
- Check hoses for signs of wear, cracks, or bulging.
- Tools Required: Flashlight, mirror.
- Safety Warning: Allow the engine to cool before inspection.
Replace Components:
- If any belts or hoses are damaged, remove them by loosening the tensioner and sliding them off.
- Install new belts or hoses, ensuring they are properly aligned and tensioned.
- Torque Values: Refer to the service manual for specific tension settings.

3. Brake Inspection

Inspect Brake Components:
- Check brake pads, rotors, and calipers for wear or damage.
- Look for signs of overheating or burned materials.
- Tools Required: Jack, jack stands, lug wrench.
Replace Worn Brake Parts:
- If brake pads are worn down, replace them with new ones.
- Ensure calipers are functioning and not sticking.
- Torque Values: Use proper torque specifications for lug nuts (typically 80-100 ft-lbs).

4. Reassemble and Reconnect

Reconnect the battery after all repairs are completed.
Ensure all components are secured and properly installed.
