Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, jack and jack stands, wrench set, screwdriver set.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Disconnect the negative battery terminal.
2. Remove any engine covers if necessary for access.
3. Loosen the tensioner using a wrench to relieve tension on the serpentine belt.
4. Remove the old serpentine belt and inspect pulleys for damage.
5. Install the new serpentine belt according to the routing diagram usually found on a label in the engine bay.
6. Re-tension the belt, ensuring it is properly aligned on all pulleys.
7. Reconnect the battery terminal.

3. Check and Replace Transmission Fluid (if applicable)

Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Locate the transmission fluid dipstick or drain plug.
3. With the engine running, remove the dipstick to check fluid condition (color and level).
4. If fluid is low or discolored, drain the old fluid using the drain plug and replace with new manufacturer-recommended fluid.
5. Reinstall the dipstick or plug and lower the vehicle.

4. Inspect and Replace Wheel Bearings (if necessary)

Sub-steps:
1. Remove the wheel to access the hub assembly.
2. Check for any play in the wheel bearings by rotating the hub.
3. If noise is detected, disassemble the hub assembly and replace the bearings.
4. Reassemble the hub with new bearings, ensuring proper torque specifications are followed.
5. Reinstall the wheel and lower the vehicle.
