Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather tools and safety gear: gloves, safety goggles, jack stands, and a socket set.

2. Inspect and Replace Engine Belts

Sub-steps:
1. Open the hood and locate the serpentine belt.
2. Visually inspect the belt for cracks, fraying, or glazing.
3. If damaged, remove the belt by loosening the tensioner pulley using a wrench.
4. Replace with a new belt, ensuring proper routing according to the belt diagram.
5. Tighten the tensioner to the manufacturer's specifications.

3. Check and Adjust Tire Conditions

Sub-steps:
1. Inspect each tire for uneven wear, cracks, or bulges.
2. Measure tire pressure using a tire gauge; inflate tires to the recommended PSI.
3. If excessive wear is present, consider replacing the tires.
4. Ensure wheel alignment and balancing are performed if necessary.

4. Inspect and Service Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for thickness and signs of overheating.
3. Check brake rotors for warping or discoloration.
4. Replace worn pads and resurface or replace rotors as needed.
5. Reassemble and torque the wheel lug nuts to specifications.
