Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely parked.
Disconnect the battery to avoid electrical issues.
Tools required: Wrench set, socket set, fluid catch pan.

2. Inspect and Replace Hoses

Sub-steps:
- Locate the power steering hoses connecting the pump to the steering rack.
- Check for any signs of wear, cracks, or leaks.
- If damaged, use a wrench to disconnect the faulty hose from both the pump and the rack.
- Replace with a new hose and ensure all connections are tight. Torque specifications typically range from 12-15 ft-lbs; consult the service manual for exact values.

3. Replace Power Steering Pump (if necessary)

Sub-steps:
- Remove the belt that drives the power steering pump by loosening the tensioner.
- Disconnect the hoses from the pump using a wrench, capturing any fluid in a catch pan.
- Remove the mounting bolts for the pump and lift it out.
- Install the new pump by reversing the removal steps and ensure all connections are secure.

4. Refill Power Steering Fluid

Sub-steps:
- Locate the power steering fluid reservoir.
- Refill with the recommended type of power steering fluid (consult owner’s manual for specifics; typically, it’s CHF 202).
- Start the engine and turn the steering wheel from lock to lock several times to purge air from the system.
- Check fluid levels again, adding more as necessary.

5. Test for Leaks

Sub-steps:
- With the engine running, inspect all connections and components for any signs of leaking fluid.
- Monitor the power steering fluid level over the next few days to ensure the issue is resolved.
