Solution

1. Preparation

Tools Required: OBD-II scanner, basic hand tools, flashlight, safety goggles, gloves
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Addressing Engine Oil Issues

Check the engine oil level using the dipstick. If low, add the appropriate type of oil as specified in the owner’s manual.
If the oil appears burnt, perform an oil change:
1. Drain the old oil using a wrench to remove the oil pan plug.
2. Replace the oil filter using an oil filter wrench.
3. Refill with new oil using the recommended type and quantity.

3. Cooling System Inspection

Inspect the coolant reservoir and radiator for leaks.
If a leak is found, replace the damaged hose or component.
Refill the coolant system with the appropriate type of coolant.

4. Brake Component Examination

Remove the wheel to access the brake assembly.
Inspect brake pads and rotors for excessive wear or burning.
Replace any damaged brake components and ensure they are properly lubricated.

5. Serpentine Belt and Pulleys

Visually check the serpentine belt for signs of wear, fraying, or burning.
If damaged, remove the belt by releasing tension on the tensioner pulley.
Replace with a new serpentine belt, ensuring proper routing and tension.
