Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Change Engine Oil (if needed)

Sub-steps:
1. Remove the oil dipstick and check the oil level; add oil if low.
2. If the oil is dirty or burnt, drain the old oil using a wrench to remove the oil pan plug.
3. Replace with the manufacturer-recommended oil type and viscosity (e.g., 5W-20).
4. Replace the oil filter if necessary.
5. Reinstall the oil pan plug and tighten to the specified torque (typically 20-25 ft-lbs).

3. Inspect and Replace Coolant (if needed)

Sub-steps:
1. Open the radiator cap and check the coolant level; add if low.
2. Inspect for leaks in the radiator and hoses.
3. If the coolant is contaminated or old, drain it and replace it with the proper coolant mixture (usually a 50/50 mix of antifreeze and distilled water).
4. Refill the radiator and reservoir, then bleed the system if necessary.

4. Brake System Inspection

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads and rotors for excessive wear or overheating.
3. Replace worn brake pads and ensure calipers are functioning properly.
4. Check for brake fluid leaks and replace fluid if discolored.

5. Inspect Belts and Hoses

Sub-steps:
1. Visually inspect belts for fraying or glazing.
2. Replace any damaged belts (e.g., serpentine belt) with the correct part.
3. Check hoses for cracks or leaks and replace as needed.
