Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Fluid

Engine Oil:
- Remove the oil drain plug using a socket set.
- Allow old oil to drain completely and replace with manufacturer-recommended oil.
- Torque the drain plug to the manufacturer's specifications (typically around 20-30 ft-lbs).
Coolant:
- Inspect the coolant reservoir for proper level.
- If low, add the appropriate coolant mixture.
- Check for leaks around hoses and the radiator.

3. Electrical Inspection

Wiring and Connectors:
- Inspect all accessible wiring for fraying or melting.
- Replace any damaged wiring with the same gauge wire.
- Clean and reconnect any corroded connectors.

4. Brake Inspection

Brake Components:
- Remove the wheel to access brake components.
- Inspect brake pads for wear; replace if less than 3mm thickness.
- Check rotors for warping or overheating; machine or replace if necessary.

5. Exhaust System Inspection

Exhaust Components:
- Inspect the exhaust system for cracks or holes, especially near the catalytic converter.
- Replace any damaged sections with OEM or equivalent parts.
