Solution

1. Preparation

Tools Required: OBD-II scanner, flashlight, socket set, torque wrench.
Safety Warnings: Ensure the engine is cool before starting any work and disconnect the battery if working on electrical components.

2. Inspect for Fluid Leaks

Use a flashlight to look for any fluid leaks around the engine, transmission, and undercarriage.
Clean any areas with leaks to identify the source effectively.
If oil is found, determine if it is engine oil, transmission fluid, or coolant.

3. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Drain the old engine oil into a pan by removing the oil drain plug (torque to specification when re-installing).
3. Replace the oil filter with a new one, ensuring the rubber O-ring is lubricated and seated properly.
4. Refill the engine with the correct type and amount of fresh engine oil.

4. Inspect and Replace Worn Components

Check the brake pads and rotors for excessive wear; replace if necessary.
Inspect the exhaust system for burnt gaskets or pipes; replace any damaged components.

5. Test Drive and Monitor

After completing repairs, perform a test drive to observe any persistent burning smell.
Monitor engine temperature and performance during the drive.
