Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and turn off the engine.
Allow the engine to cool down if it has been running.
Tools Required: Socket set, wrench set, fluid catch pan, OBD-II scanner.

2. Inspect and Replace Leaking Hoses

Locate the Power Steering Hoses:
- Identify high-pressure and return hoses connected to the power steering pump and steering gear.
Remove Damaged Hoses:
- Use the appropriate wrench to detach the hose clamps and slide them away from the hoses.
- Carefully pull the hoses off the fittings and allow any remaining fluid to drain into the catch pan.
Install New Hoses:
- Slide the new hoses onto the fittings and secure them with hose clamps.
- Ensure the clamps are tightened to prevent future leaks (typically 10-15 Nm torque).

3. Replace the Power Steering Pump (if necessary)

Remove the Old Pump:
- Disconnect the negative battery cable to prevent electrical shorts.
- Unplug the electrical connector from the pump.
- Remove the mounting bolts and lift the pump out.
Install New Pump:
- Position the new pump in place and secure it with mounting bolts (torque to manufacturer specifications).
- Reconnect the electrical connector.

4. Top Off Power Steering Fluid

Fill the Reservoir:
- Using the appropriate type of power steering fluid (refer to the owner's manual), fill the reservoir to the recommended level.
Bleed the System:
- Start the engine and turn the steering wheel from lock to lock several times to remove air from the system.
- Check fluid levels again and add more if necessary.
