Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool down if it has been running.

2. Inspect and Replace Damaged Components

Inspect Belts and Hoses:
- Check for cracks, fraying, or signs of melting.
- If damaged, replace with OEM parts.
Replace Worn Tires:
- Measure tread depth; if below the legal limit, replace tires.
- Ensure proper tire pressure and alignment.
Brake System Inspection:
- Remove the wheels to access brake components.
- Inspect brake pads and rotors for wear; replace if necessary.
- Lubricate caliper slides and ensure they move freely.

3. Electrical System Check

Inspect the alternator and wiring for signs of overheating.
If the alternator is damaged, replace it with a compatible unit.
Ensure all electrical connections are secure and free from corrosion.

4. Clean Up and Finalize

Remove any debris found in the engine bay or undercarriage.
Reconnect the battery and ensure that all tools are removed from the work area.
