Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Replace Components

A. Serpentine Belt Inspection

Remove the engine cover (if applicable) using a socket set.
Visually inspect the serpentine belt for cracks or wear.
If damaged, replace the belt:
- Loosen the tensioner using a ratchet and socket.
- Remove the old belt and install the new belt according to the routing diagram.
- Reapply tension and ensure proper alignment.

B. Brake Component Inspection

Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake assembly.
Check brake pads and calipers for excessive wear or overheating signs.
If pads are worn down, replace them:
- Remove caliper bolts with a socket set.
- Slide the caliper off and replace the brake pads.
- Reinstall the caliper and tighten bolts to manufacturer specifications.

C. Tire Inspection

Inspect tires for uneven wear or damage.
Ensure proper tire pressure and alignment.
If any tires show signs of rubbing, adjust the suspension or wheel alignment as necessary.

3. Reassemble and Test

Reinstall the wheels and lower the car.
Reconnect the battery.
Start the engine and check for any abnormal sounds or smells.
Conduct a test drive to ensure the issue is resolved.
