Solution

1. Preparation

Tools Needed: Socket set, flashlight, OBD-II scanner
Ensure the vehicle is parked on a level surface with the engine off and cool.

2. Inspect and Replace Damaged Belts

Sub-steps:
1. Open the hood and visually inspect all serpentine and timing belts for cracks, fraying, or signs of wear.
2. If a belt is damaged, release tension using a wrench to loosen the tensioner.
3. Remove the old belt and install a new belt, following the routing diagram typically found on a sticker in the engine bay.
4. Tighten the tensioner to the manufacturer's specifications (usually around 20-30 lbs of pressure).

3. Check and Replace Damaged Hoses

Sub-steps:
1. Inspect all rubber hoses for any signs of wear, leaks, or melting.
2. If any hoses are damaged, remove the old hose clamps and replace the damaged hose with a new one.
3. Ensure all connections are secure and replace any hose clamps.

4. Brake Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure with jack stands.
2. Remove the wheel to access the brake components.
3. Inspect the brake pads and caliper for excessive wear or binding.
4. Replace any worn out brake pads or components, ensuring all parts are correctly torqued to specifications.
