Solution

1. Preparation

Tools Required: Safety gloves, safety goggles, floor jack, jack stands, OBD-II scanner
Ensure the vehicle is parked on a level surface and the engine is off. Allow the engine to cool completely before proceeding.

2. Inspect and Replace Engine Oil

Check Oil Level: Use the dipstick to check the engine oil level and condition.
Change Oil if Necessary: If the oil is low or burnt, drain the old oil using a wrench to remove the oil drain plug. Replace with new oil as specified in the owner's manual.
- Torque Specification: Reinstall the oil drain plug to the manufacturer’s torque specification.

3. Check and Replace Coolant

Inspect Coolant Level: Open the radiator cap (only when cool) and check the coolant level.
Top Off or Replace Coolant: If low, add coolant to the appropriate level. If the coolant appears dirty or contaminated, perform a coolant flush and replace with fresh coolant.
- Fluid Type: Use the recommended type of coolant specified in the owner's manual.

4. Inspect and Service the Brake System

Check Brake Components: Inspect brake pads and calipers for signs of wear or overheating.
Replace or Service: If calipers are sticking, clean or replace them as necessary. Ensure brake fluid is at the correct level and condition.
- Fluid Type: Use DOT 3 or DOT 4 brake fluid, as specified.

5. Inspect Electrical Components

Examine Wiring: Look for frayed wires or burnt connections in the engine compartment.
Repair or Replace: If any damaged wiring or components are found, repair or replace them to prevent further issues.
