Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Fluids

Engine Oil:
- Remove the oil drain plug using a socket set and drain the oil into a pan.
- Replace the oil filter using an oil filter wrench.
- Refill with the appropriate type and amount of engine oil (consult owner’s manual).
Coolant:
- Check the coolant level in the reservoir.
- If low, drain the old coolant from the radiator, flush the system, and refill with a 50/50 mix of coolant and distilled water.

3. Brake Inspection and Replacement

Remove the wheel to access the brake components.
Inspect brake pads, rotors, and calipers for signs of wear or overheating.
Replace any worn brake pads and resurface or replace rotors as necessary.

4. Electrical Inspection

Check the wiring harness for any signs of melting or chafing.
Replace any damaged wires or connectors with appropriate automotive-grade components.

5. Belts and Hoses Inspection

Inspect belts for fraying or cracking; replace if necessary.
Check hoses for leaks or wear; replace any that show signs of damage.
