Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool before starting work.

2. Inspect and Clean Engine Bay

Remove any debris or obstructions from the engine bay.
Use a degreaser to clean any oil or fluid residue that may be contributing to the burning smell.

3. Check and Replace Fluid Levels

Coolant: If low, refill with the appropriate coolant mixture (50/50 water and antifreeze).
Oil: Check the oil level; if low, add the correct type of oil (consult the owner's manual for specifications).

4. Replace Worn Belts and Hoses

Visually inspect belts for fraying or cracking. Replace any damaged belts.
Inspect hoses for leaks or wear, and replace if necessary.

5. Brake Inspection

Remove the wheel to access the brake components.
Inspect pads and rotors for excessive wear. Replace if they are worn or burnt.

6. Reassemble and Test

Reattach any components removed during inspection.
Start the engine and monitor for any smells, smoke, or unusual noises.
