Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, fluid containers, funnel, and safety gloves.
Park the vehicle on a flat surface and engage the parking brake.
Allow the engine to cool down if it has been running.

2. Fluid Level Check

Transmission Fluid:
- Locate the transmission dipstick.
- Remove and wipe the dipstick clean, reinsert, and then remove again to check the fluid level.
- Top off with the recommended transmission fluid if low (refer to owner's manual for specifications).
Power Steering Fluid:
- Locate the power steering fluid reservoir.
- Check the fluid level against the markings on the reservoir.
- Add the appropriate power steering fluid if necessary.

3. Serpentine Belt Inspection

Use a socket set to remove the serpentine belt tensioner.
Inspect the belt for any cracks, fraying, or glazing.
If damaged, replace the serpentine belt with a new one, ensuring proper routing according to the diagram under the hood.

4. Power Steering Pump Replacement (if needed)

Remove Old Pump:
- Disconnect the battery.
- Drain the power steering fluid into a container.
- Unbolt the power steering pump from its mount using a socket set.
- Disconnect the hoses and remove the pump.
Install New Pump:
- Install the new power steering pump and secure it with bolts.
- Reconnect the hoses and ensure they are tight.
- Refill the power steering reservoir with the recommended fluid.

5. Final Checks

Start the engine and turn the steering wheel from lock to lock to bleed air from the system.
Check for any leaks around the pump and fluid levels.
