1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Identify Source of Smell

Sub-steps:
1. Open the hood and visually inspect for any smoke or burning components.
2. Look for burned wires, melted plastic, and components that appear discolored.
3. Check for any fluid leaks, particularly oil or coolant, and trace their source.

3. Addressing Electrical Issues

Sub-steps:
1. Repair or replace any damaged wiring or connectors found during inspection.
2. If a short circuit is suspected, isolate the affected circuit and replace the faulty components.
3. Use electrical tape or heat-shrink tubing to secure any repaired sections.

4. Cooling System Check

Sub-steps:
1. Inspect the radiator and hoses for leaks; replace any damaged hoses or the radiator as necessary.
2. Flush the cooling system if coolant is contaminated or low, and refill with the appropriate coolant mixture.
3. Ensure the thermostat is functioning correctly; replace if faulty.

5. Engine Oil Service

Sub-steps:
1. Change the engine oil and filter if oil is burnt or degraded.
2. Refill with the manufacturer-recommended oil type and quantity.
3. Inspect the oil pan for leaks and repair as needed.
