Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Gather all necessary tools and safety equipment (gloves, safety glasses).

2. Inspect and Identify Source of Smell

Open the hood and visually inspect for any burnt components, melted wiring, or leaking fluids.
Look for any signs of smoke or burnt hoses.
If the burning smell is related to brakes, visually inspect the brake pads, rotors, and calipers for excessive wear or overheating.

3. Address Leaks or Damaged Components

If any leaks are found, identify the source (e.g., oil pan gasket, transmission seal) and proceed with repairs or replacement.
For burnt components (like wiring), replace damaged wires or connectors.
If brake components are worn, replace brake pads and/or rotors as necessary.

4. Fluid Replacement

If engine oil or transmission fluid appears burnt, drain the old fluid completely.
Replace with manufacturer-recommended fluids, ensuring proper levels are maintained.
Dispose of old fluids in accordance with local regulations.

5. Reassemble and Test

Reassemble any components removed during inspection and repairs.
Start the engine and allow it to reach operating temperature.
Monitor for any continued smells or unusual noises.
