- Remove the old hose and replace it with a new one, ensuring it fits securely.
- Re-secure the clamps to the proper torque specifications.
For a leaking power steering pump:
- Disconnect the pump from its mounting bracket.
- Remove the inlet and outlet lines.
- Install the new pump and reconnect the lines, ensuring all connections are tight.

4. Refill Power Steering Fluid

Using a funnel, refill the power steering reservoir with the manufacturer-recommended fluid type.
Tools Required: Funnel, new power steering fluid.

5. Bleed Power Steering System

Start the engine and turn the steering wheel from lock to lock several times to remove air from the system.
Check fluid levels and top off as necessary.
