Install the new power steering pump by reversing the removal steps; ensure lines are securely fastened and the pump is properly aligned.
Reconnect the battery.

4. Bleed the Power Steering System

With the engine running, turn the steering wheel from lock to lock several times to purge air from the system.
Check fluid levels again and top off as necessary.
