Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Power steering fluid
- OBD-II scanner
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Refill Power Steering Fluid

Remove the power steering fluid reservoir cap.
Inspect fluid level; if low, add manufacturer-recommended power steering fluid.
If fluid is dirty or contaminated, proceed to the next step.

3. Inspect and Replace Power Steering Fluid

Locate the power steering pump and hoses.
Disconnect the return hose and allow the old fluid to drain into a container.
Reconnect the return hose, ensuring it is secure.
Fill the reservoir with new power steering fluid to the appropriate level.

4. Inspect and Replace Power Steering Pump (if necessary)

Remove the drive belt from the power steering pump.
Disconnect the power steering lines from the pump using the socket set.
Remove the mounting bolts and take out the pump.
Install the new pump by reversing the removal steps. Ensure all connections are tight.

5. Reconnect and Test

Reconnect the negative battery terminal.
Start the engine and turn the steering wheel from lock to lock to bleed the system of air.
Check fluid level again and top off as necessary.
