Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, socket set, torque wrench, multimeter.
Ensure the vehicle is on a flat surface and securely raised with jack stands.
Allow engine to cool before beginning work.

2. Inspect and Replace Serpentine Belt (if necessary)

Sub-steps:
1. Remove the engine cover (if equipped) by unscrewing any bolts.
2. Use a socket set to release tension on the serpentine belt tensioner.
3. Carefully remove the serpentine belt from the pulleys.
4. Inspect the belt for cracks, fraying, or glazing; replace if damaged.
5. Install the new serpentine belt according to the belt routing diagram.
6. Reapply tension using the belt tensioner and ensure it operates smoothly.

3. Check and Top Up Fluids

Sub-steps:
1. Locate the transmission dipstick and check fluid level; add fluid as necessary.
2. Inspect the power steering fluid reservoir and top off if low.
3. Check the differential fluid level; replace if dirty or low.
4. Ensure all fluids meet manufacturer specifications for type and quantity.

4. Inspect Wheel Bearings and Hubs

Sub-steps:
1. Raise the vehicle and securely support it on jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the wheel bearings for play by trying to move the wheel up and down; replace if excessive play is observed.
4. Check for any visible damage or wear on the hub assembly.
5. Reinstall the wheels and torque the lug nuts to manufacturer specifications.
