Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather tools and safety equipment: gloves, safety glasses, rags.
Allow the engine to cool before beginning work.

2. Inspect and Repair Engine Components

Inspect Engine Oil:
- Remove the dipstick and check oil level and condition.
- If burnt oil is present, drain the oil and replace it with new oil (use manufacturer-recommended oil type).
- Replace oil filter if necessary.
Inspect Belts and Hoses:
- Visually check for cracks or fraying.
- Replace any damaged belts or hoses as needed.

3. Examine Brake System

Check Brake Pads and Rotors:
- Remove the wheel to access brake components.
- Inspect brake pads for wear and replace if they are below the manufacturer’s minimum thickness.
- Check rotors for overheating or warping; replace if necessary.

4. Examine Transmission Fluid

Check Transmission Fluid:
- Locate the transmission dipstick (if applicable) and check fluid level and condition.
- If burnt, drain the old fluid and replace it with new transmission fluid, ensuring to use the correct type specified by the manufacturer.

5. Final Inspection

After repairs, perform a visual inspection to ensure all components are secure and properly installed.
Start the engine and allow it to reach operating temperature while monitoring for any further smells.
