Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool before starting.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Worn Rubber Components

Inspect Belts:
- Remove the engine cover if necessary.
- Check the serpentine belt for cracks or signs of melting.
- If damaged, remove the belt by loosening the tensioner pulley.
Replace Belt:
- Install a new serpentine belt following the routing diagram.
- Tighten the tensioner pulley to the specified torque (typically around 15-20 Nm).

3. Verify Brake Components

Inspect Brake Pads and Rotors:
- Remove the wheel to access brake components.
- Check for wear on brake pads; replace if they are excessively worn.
- Inspect rotors for overheating signs (blue discoloration) and replace if necessary.

4. Cooling System Check

Inspect Hoses and Radiator:
- Examine all rubber hoses for cracks or leaks.
- Replace any damaged hoses with OEM replacement parts.
- Check the radiator for blockages or leaks, and clean or replace as needed.
