Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid catch pan, flashlight, and safety gloves.
Ensure the vehicle is on a flat surface and the engine is off. Disconnect the 12V battery for safety.

2. Fluid Level Check

Locate the power steering fluid reservoir under the hood.
Remove the cap and check the fluid level against the markings on the reservoir.
If the fluid is low, top it up with the recommended power steering fluid as specified in the owner's manual.

3. Inspect the Power Steering Pump

Visually inspect the power steering pump for signs of wear or damage.
Check all hoses and connections for leaks or cracks.
If leaks are found, proceed to replace the affected hoses or the pump.

4. Pump Replacement (if necessary)

Tools Required: Socket set, torque wrench, fluid catch pan.
Remove any components obstructing access to the power steering pump (e.g., engine covers).
Disconnect the power steering hoses from the pump, using the fluid catch pan to catch any spills.
Unbolt the power steering pump from its mounting bracket.
Install the new power steering pump by reversing the removal steps, ensuring all connections are secure and torqued to specifications.

5. Final Check and Refill

Reconnect the 12V battery and start the engine.
Turn the steering wheel from lock to lock several times to bleed air from the system.
Check fluid levels again and add more if necessary.
