Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, brake cleaner, flashlight, and a multimeter.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Brake Pads

Lift the vehicle: Use a jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Remove the wheel: Use a socket set to take off the lug nuts and remove the wheel.
Check brake pads: Inspect the pads for thickness. If they are worn down to 3mm or less, replace them.
- Tools Required: Brake pad spreader (if necessary).
Clean components: Use brake cleaner to clean the brake pads and rotor surface.
Reinstall: Place new brake pads in the caliper, ensuring they are properly seated.
Reattach the wheel: Put the wheel back on, hand-tighten the lug nuts, and lower the vehicle.

3. Inspect and Replace Serpentine Belt

Access the engine bay: Open the hood and locate the serpentine belt.
Check the belt: Look for cracks, frays, or signs of wear.
Remove the belt: Use a socket or wrench to relieve tension on the tensioner pulley and remove the belt from the pulleys.
Install new belt: Replace with a new serpentine belt, following the routing diagram usually found on a sticker in the engine bay.
Recheck tension: Ensure the belt is properly tensioned according to the specifications.
