Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Allow the engine to cool if it has been running.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Locate the serpentine belt routing diagram (typically found on a sticker in the engine compartment).
2. Release tension from the belt using a wrench or ratchet on the tensioner pulley.
3. Carefully remove the serpentine belt from all pulleys.
4. Inspect the belt for signs of wear or damage; replace if necessary.
5. Install the new belt according to the routing diagram, ensuring proper tension.

Tools Required:

Wrench set
New serpentine belt (if needed)

3. Inspect Brake Components

Sub-steps:
1. Safely lift the vehicle and remove the wheel to access the brake assembly.
2. Inspect brake pads for wear; replace if they are worn down to the indicator.
3. Check the calipers for proper operation; ensure they are not sticking.
4. Inspect the brake rotor for overheating signs (blue discoloration); replace if necessary.

Tools Required:

Jack and jack stands
Lug wrench
Brake cleaner
New brake pads/rotors (if needed)

4. Check Tires

Sub-steps:
1. Inspect all tires for signs of uneven wear or damage.
2. Ensure tire pressure is at the manufacturer’s recommended levels.
3. Check wheel alignment and balance; adjust if needed.

Tools Required:

Tire pressure gauge
