Solution

1. Preparation

Tools Required: Socket set, fluid catch pan, funnel, OBD-II scanner, torque wrench
Park the vehicle on a flat surface and turn off the engine. Allow the engine to cool if it has been running.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Fluid Check and Replacement

Sub-steps:
1. Locate the power steering fluid reservoir. Remove the cap and check the fluid level.
2. If the fluid is low, add the recommended power steering fluid (check owner’s manual for the correct type).
3. If fluid is dark or contaminated, proceed to drain and replace it.
4. Place a fluid catch pan under the power steering pump. Disconnect the return line and allow old fluid to drain completely.
5. Reconnect the return line securely.

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

Sub-steps:
1. Remove any components obstructing access to the power steering pump (e.g., air intake duct).
2. Detach the pump from its mounting by removing the securing bolts (torque specifications found in the service manual).
3. Disconnect the power steering lines from the pump.
4. Install the new power steering pump by reversing the removal steps, ensuring all connections are tight.
5. Torque the bolts to the specified value from the service manual.

4. Check for Leaks

After reinstalling the pump and reconnecting all hoses, refill the power steering fluid reservoir to the recommended level.
Start the engine and let it idle. Turn the steering wheel from lock to lock several times to bleed air from the system.
Check for leaks around the pump, hoses, and rack.

5. Final Checks

Reconnect the negative battery terminal.
Start the vehicle and recheck the fluid level, adding more fluid as necessary.
Ensure that the power steering warning light is off.
