Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, OBD-II scanner, multimeter.
Ensure the vehicle is parked on a flat surface and the engine is cool before beginning work.

2. Inspect and Replace Worn Components

A. Tires

Check for uneven wear or damage.
If necessary, replace tires that are worn out or damaged.

B. Brake System

Remove the wheel to access the brake assembly.
Inspect brake pads and rotors for wear; replace pads if they are worn below the manufacturer’s minimum thickness.
Check calipers for proper operation; replace if they are sticking.

C. Engine Belts

Inspect all belts for fraying or wear.
If found damaged or misaligned, replace the belt with the correct OEM specification belt.

3. Address Fluid Issues

Check engine oil, transmission fluid, and coolant levels.
If low, top off using the manufacturer's recommended fluids; if leaks are present, locate and repair leaks.

4. Reassemble and Test

Reinstall any components or wheels that were removed.
Ensure all fasteners are torqued to the manufacturer’s specifications.
Start the vehicle and allow it to reach operating temperature while monitoring for any unusual smells or noises.
