Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, flashlight, safety goggles, gloves.
Allow the vehicle to cool down before starting any inspection.

2. Inspect and Replace Belts

Sub-steps:
1. Open the hood and locate the serpentine and accessory belts.
2. Inspect the belts for signs of wear, such as cracks or fraying.
3. If damaged, loosen the tensioner using a socket and remove the old belt.
4. Install the new belt according to the routing diagram found on the engine bay.
5. Tighten the tensioner to the manufacturer's specifications.

3. Check and Replace Tires

Sub-steps:
1. Inspect all tires for uneven wear, bulges, or items lodged in the tread.
2. If a tire is damaged, remove it using a jack and socket set.
3. Replace the tire with a new one, ensuring proper torque specs (usually around 80-100 ft-lbs).
4. Re-check alignment and balance if necessary.

4. Inspect Brake System

Sub-steps:
1. Remove the wheel to access the brake caliper.
2. Check the brake pads and rotors for signs of excessive wear or overheating.
3. If the pads are worn, replace them with high-quality replacements.
4. Ensure calipers move freely and do not bind; lubricate if necessary.
