Solution

1. Preparation

Tools Required: Basic hand tools (sockets, wrenches), OBD-II scanner, multimeter, shop towels, coolant catch pan.
Allow the engine to cool completely before starting any work.

2. Identify the Source of the Burning Smell

Sub-steps:
1. Open the hood and visually inspect for any smoke or signs of burning.
2. Use the OBD-II scanner to check for any trouble codes and record them for further analysis.
3. Inspect the engine oil dipstick for burning odor and check oil level; top off or replace as necessary.

3. Address Oil Leaks

Sub-steps:
1. If oil leaks are identified, locate the source (e.g., oil pan gasket, valve cover gasket).
2. Clean the area around the leak with shop towels and allow it to dry.
3. Replace any damaged gaskets or seals as needed, ensuring proper torque specifications when reinstalling.

4. Inspect Electrical Components

Sub-steps:
1. Visually inspect wiring and connectors for damage or melting.
2. Use a multimeter to check for continuity in damaged wires and replace as necessary.
3. Secure any loose connections and ensure that all electrical components are properly insulated.

5. Check Cooling System

Sub-steps:
1. Inspect the coolant level in the reservoir; top off with the appropriate 50/50 coolant mixture if necessary.
2. Look for any leaks in the radiator or hoses; replace any damaged components.
3. Inspect the water pump for proper function and replace if it is leaking or not operational.
