Solution

1. Preparation

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

2. Inspect and Repair Engine Components

Inspect Oil: Check the engine oil level and condition. If burnt oil is present:
- Drain the old oil using an oil pan.
- Replace with new oil according to manufacturer specifications.
Inspect Hoses and Belts: Check for any signs of wear or burning:
- Replace any damaged hoses or belts. Use proper size and type as per specifications.

3. Brake System Inspection

Remove Wheel: Use a jack and jack stands to safely lift the vehicle and remove the wheel to access the brake components.
Inspect Brake Pads and Rotors: Look for signs of overheating:
- Replace brake pads if they are worn down or cracked.
- Resurface or replace rotors if they show signs of excessive wear or heat damage.

4. Transmission Fluid Check

Inspect Transmission Fluid: Remove the dipstick and check fluid level and condition.
- If the fluid is burnt or low, drain the old fluid and replace it with new, manufacturer-recommended transmission fluid.

5. Final Assembly

Reassemble any components or wheels that were removed.
Reconnect the negative battery terminal.
