Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Gather necessary tools and parts.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, serpentine belt tool
Locate the serpentine belt tensioner and use the serpentine belt tool to relieve tension.
Remove the old serpentine belt from the pulleys and inspect for cracks or fraying.
Install the new serpentine belt, ensuring it follows the correct routing diagram.
Reapply tension to the belt using the tensioner and double-check alignment.

3. Examine and Repair Brake System

Tools Required: Jack, jack stands, lug wrench, torque wrench
Lift the vehicle using a jack and secure with jack stands.
Remove the wheel to access the brake components.
Inspect the brake pads, rotors, and calipers for any signs of wear or sticking.
Replace any worn components and ensure brake calipers move freely.
Reassemble the wheel and lower the vehicle, tightening lug nuts to the manufacturer's specified torque.

4. Check and Replace Damaged Rubber Components

Inspect hoses, grommets, and other rubber parts in the engine compartment for wear.
Replace any damaged hoses or components with OEM or high-quality aftermarket parts.
