Solution

1. Preparation

Ensure the vehicle is parked on a flat surface, turn off the engine, and allow it to cool.
Gather tools and safety equipment: gloves, safety goggles, OBD-II scanner, socket set, and multimeter.

2. Addressing Engine Oil Issues

Check Oil Level
- Remove the dipstick, wipe it clean, reinsert, and check the oil level.
- If low, top off with the manufacturer-recommended oil type.
Change Oil and Filter (if burnt)
- Place an oil drain pan under the oil pan.
- Remove the drain plug and let old oil drain completely.
- Replace the oil filter using an oil filter wrench.
- Reinstall the drain plug and refill with new engine oil to the correct level.

3. Inspecting and Repairing Cooling System

Check Coolant Level
- Inspect the coolant reservoir and radiator for low levels or leaks.
- If low, add a 50/50 mix of coolant and distilled water.
Inspect Hoses and Radiator
- Visually inspect hoses for cracks or leaks; replace any damaged hoses.
- Check the radiator for blockages or leaks; flush if necessary.

4. Brake System Inspection

Inspect Brake Pads and Rotors
- Remove the wheel to access brakes.
- Check the thickness of brake pads; replace if worn down.
- Inspect rotors for scoring or warping and resurface or replace as necessary.

5. Electrical System Check

Inspect Wiring and Connections
- Examine the wiring harness for any signs of melting or damage.
- Repair or replace any damaged wires or connectors as needed.
Check Battery and Alternator
- Test the battery voltage with a multimeter; replace if voltage is low.
- Inspect the alternator for signs of overheating or damage; replace if faulty.
