Solution

1. Preparation

Tools Required: Wrench set, power steering fluid, OBD-II scanner, clean rags.
Ensure the vehicle is parked on a level surface and the engine is off before beginning work.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir and remove the cap.
2. Use a clean rag to wipe the dipstick or check the fluid level marked on the side of the reservoir.
3. If the fluid is low, add the manufacturer-recommended power steering fluid until it reaches the appropriate level.

3. Check and Replace Power Steering Pump

Sub-steps:
1. Disconnect the negative battery terminal to prevent electrical shorts.
2. Remove the serpentine belt by loosening the tensioner and sliding the belt off the power steering pump pulley.
3. Disconnect the high-pressure and low-pressure lines from the pump using the appropriate wrench.
4. Remove the mounting bolts that secure the pump to the engine and carefully take the pump out.
5. Install the new power steering pump by reversing the removal steps, ensuring all bolts are torqued to the manufacturer's specifications (usually around 17-23 Nm).
6. Reconnect the power steering lines and the serpentine belt.
7. Reconnect the battery terminal.

4. Bleed the Power Steering System

Sub-steps:
1. Fill the power steering reservoir with the correct fluid.
2. Start the engine and turn the steering wheel from lock to lock several times to remove air from the system.
3. Check the fluid level and add more if necessary.
