Solution

1. Preparation

Park the vehicle on a flat surface and allow the engine to cool completely.
Gather tools: socket set, OBD-II scanner, rags, coolant, and engine oil.

2. Inspect and Identify Source of Burning Smell

Open the hood and perform a visual inspection of the engine components.
Look for burnt oil on the engine block or components, and check for melted wires or connectors.
Use a flashlight to inspect areas that are difficult to see, such as behind the engine.

3. Address Fluid Leaks

If oil is leaking, locate the source (e.g., valve cover gasket, oil pan).
- Sub-steps:
  1. Clean the area around the leak with rags.
  2. Replace the faulty gasket or seal as necessary.
  3. Refill oil to the appropriate level.
If coolant is leaking, inspect hoses and the radiator for damage.
- Sub-steps:
  1. Replace any damaged hoses using appropriate clamps.
  2. Repair or replace the radiator if necessary.
  3. Refill the cooling system with the manufacturer's recommended coolant type.

4. Electrical Inspection

If electrical issues are suspected, inspect the wiring harness and connectors.
- Sub-steps:
  1. Disconnect the battery before working on electrical systems.
  2. Replace any damaged wiring or connectors.
  3. Secure all connections to prevent further issues.

5. Final Checks

Recheck fluid levels after repairs.
Start the engine and allow it to run while monitoring for any burning smells or leaks.
Test drive the vehicle to ensure proper operation.
