Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and parts.

2. Inspect and Repair Engine Components

Tools Required: Socket set, torque wrench, mechanic's gloves.
Sub-steps:
1. Open the hood and visually inspect for oil or coolant leaks.
2. If leaks are detected, identify the source (e.g., oil filter, gaskets).
3. Replace any defective gaskets or seals as needed, ensuring proper torque specifications.
4. Refill any lost fluids to the correct levels.

3. Inspect and Replace Brake Components

Tools Required: Jack and jack stands, lug wrench, socket set.
Sub-steps:
1. Safely lift the vehicle and remove the wheel to access the brake assembly.
2. Inspect brake pads for thickness; if less than 3mm, replace pads.
3. Check the rotors for scoring; if damaged, replace rotors.
4. Reassemble the brake components and ensure proper torque on lug nuts (usually 80-100 ft-lbs).

4. Inspect Electrical System

Tools Required: Multimeter, wire strippers, electrical tape.
Sub-steps:
1. Visually inspect all wiring harnesses for signs of damage.
2. Use a multimeter to check for short circuits or abnormal voltage.
3. Repair or replace any damaged wires and secure connections.
4. Use electrical tape to insulate any exposed wires.

5. Inspect Belts and Hoses

Tools Required: Mechanic's gloves.
Sub-steps:
1. Check all belts for cracks, fraying, or glazing.
2. Replace any damaged belts with OEM specifications.
3. Inspect hoses for leaks or deterioration and replace as needed.
