- If damaged, remove the belt using a ratchet and socket to release the tensioner.
- Replace with a new serpentine belt, ensuring proper alignment on all pulleys.
Examine Engine Hoses:
- Inspect all rubber hoses for signs of cracking or wear.
- Replace any damaged hoses with OEM parts, securing them with proper clamps.

3. Brake System Inspection

Visual Inspection:
- Check brake pads and rotors for excessive wear or overheating signs.
- Listen for squealing sounds that may indicate worn brake pads.
Replace Brake Pads (if necessary):
- Remove the wheel using a lug wrench.
- Remove the caliper using a socket and ratchet.
- Replace the brake pads and reassemble the caliper, ensuring proper torque specifications are followed.
