Solution

1. Preparation

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

2. Inspect and Identify Source of Burning Smell

Sub-steps:
1. Open the hood and visually inspect for any signs of burnt wiring or components.
2. Check for oil leaks around the engine and oil pan; if oil is leaking, clean the area and monitor for further leaks.
3. Inspect the exhaust system for any signs of burnt insulation or components that could be causing the smell.

3. Address Engine Oil Issues

Sub-steps:
1. If the oil level is low, add the correct type of engine oil as specified in the owner’s manual.
2. If the oil appears burnt or contaminated, perform an oil change:
  - Drain the old oil and replace it with new oil.
  - Replace the oil filter using an oil filter wrench.
  - Refill with the appropriate amount of new oil (check for the correct capacity in the owner’s manual).

4. Check Transmission Fluid

Sub-steps:
1. If the transmission fluid is low or burnt, drain and replace it, ensuring to use the correct type of fluid.
2. Inspect the transmission cooler lines for leaks; replace any damaged lines.

5. Brake Inspection

Sub-steps:
1. Remove the wheel to inspect the brake pads and rotors for excessive wear or overheating.
2. If the pads are worn down or if there is a burning smell coming from the brakes, replace the brake pads and rotors as necessary.
