Solution

1. Preparation

Gather tools and park the vehicle on a level surface.
Ensure the engine is cool before beginning any inspections.
Tools Required: Basic hand tools, OBD-II scanner, fluid catch pan.

2. Inspect Engine Compartment

Open the hood and visually inspect for leaks.
Check engine oil, coolant levels, and transmission fluid levels.
If any fluid is low, top it up with the recommended fluid type.

3. Check Belts and Hoses

Inspect all belts for cracks, fraying, and proper tension.
Check hoses for bulging, cracks, or leaks.
Replace any damaged belts or hoses as necessary.

4. Inspect Brake System

Remove the wheel to access the brake components.
Check the brake pads for wear; replace if they are worn down to the metal.
Inspect brake rotors for overheating signs (blue discoloration).
Replace brake pads and resurface or replace rotors as needed.

5. Analyze Transmission Fluid

Remove the transmission dipstick and check the fluid color and smell.
If the fluid is dark or smells burnt, perform a transmission fluid change.
Replace the transmission filter if applicable.

6. Exhaust System Inspection

Visually inspect the exhaust system for any leaks or holes.
Repair or replace damaged sections of the exhaust as necessary.
