Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is on a flat, stable surface with the parking brake engaged.
Allow the engine to cool down completely before proceeding.

2. Inspect and Replace Fluids

Oil Inspection and Replacement:
- Check the engine oil level with the dipstick.
- If oil is low or contaminated, drain the old oil using a socket set, replace the oil filter, and refill with the manufacturer's recommended oil type.
Coolant Check:
- Inspect the coolant level in the reservoir; if low, top off with the specified coolant type.

3. Examine and Replace Worn Components

Belts and Hoses:
- Inspect all belts for fraying or cracking; replace if necessary using a belt tensioner tool.
- Check hoses for leaks or damage; replace any compromised hoses.

4. Address Electrical Issues

Wiring Inspection:
- Look for exposed wires or burnt connectors, especially in the engine bay.
- Repair or replace any damaged wiring with appropriate connectors and heat-shrink tubing.

5. Brake System Inspection

Brake Pad and Rotor Check:
- Lift the vehicle and remove the wheels to inspect brake pads and rotors for excessive wear.
- Replace worn brake pads and resurface or replace rotors as necessary.
