Solution

1. Preparation

Tools Required: OBD-II scanner, flashlight, rags, safety goggles, gloves.
Allow the engine to cool down before starting any work.
Disconnect the battery to ensure safety while inspecting electrical components.

2. Inspect Engine Bay

Open the hood and visually inspect for any burnt oil or fluid leaks.
Look for any electrical wires that may be frayed or damaged.
Check the exhaust system for any signs of burning or melting.

3. Address Fluid Leaks

If oil is leaking, clean the area and determine the source (e.g., valve cover gasket, oil pan).
Replace any damaged gaskets or seals that may be leaking.
Ensure that all fluids (engine oil, coolant, transmission fluid) are at the proper levels.

4. Inspect Belts and Hoses

Examine all belts for fraying or signs of wear; replace if necessary.
Check hoses for cracks or leaks; replace damaged hoses.

5. Transmission Fluid Check

With the engine warmed up, check the transmission fluid level using the dipstick.
If the fluid is low, top it off with the manufacturer's recommended type.
If the fluid is burnt, consider flushing the transmission and replacing it.
