Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Serpentine Belt (if worn)

Sub-steps:
- Locate the serpentine belt and check for signs of wear, cracks, or fraying.
- If the belt is damaged, remove the tensioner bolt using a socket wrench to release tension.
- Carefully remove the old belt and install the new belt following the routing diagram.
- Reapply tension to the belt and ensure it is seated correctly.

3. Check and Replace Tires (if necessary)

Sub-steps:
- Inspect each tire for uneven wear patterns, bulges, or foreign objects.
- If a tire shows signs of damage or excessive wear, remove the wheel using a lug wrench.
- Replace with a new tire, ensuring it is properly inflated and balanced.
- Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.

4. Inspect and Replace Brake Pads (if needed)

Sub-steps:
- Remove the wheel to access the brake components.
- Inspect the brake pads for thickness and signs of wear.
- If the pads are worn, remove the caliper bolts and lift the caliper off the rotor.
- Replace the old pads with new ones and reassemble the caliper.
- Ensure proper seating of the caliper and torque bolts to specification.
