Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool.
Remove the belt from the tensioner, noting the routing path.
Inspect the belt for signs of wear (cracks, fraying).
If damaged, replace with a new belt, ensuring proper routing and tension.

3. Check and Replace Brake Components

Tools Required: Jack and jack stands, socket set, torque wrench.
Safely lift the vehicle and remove the wheel.
Inspect brake pads and rotors for wear; replace pads if less than 3mm thick or if uneven wear is observed.
Resurface or replace rotors if they show signs of overheating (blue discoloration).
Reinstall the wheel and lower the vehicle to the ground.

4. Inspect Engine Components

Tools Required: Multimeter (if electrical issues suspected), flashlight.
Inspect hoses and wiring for signs of wear or melting.
Replace any damaged hoses or connectors.
Reconnect the battery terminal.
