Add fluid (if necessary): If the fluid seems to go down, you may need to add some more fluid so that the reservoir doesn’t empty.

Go on with steps 6 and 7 some more: Turn the steering and check the fluid level some more until you can no longer see any more bubbles.

Turn off the engine: Once you are satisfied that the air bubbles are out completely, turn off the car’s engine. There you go; you’ve just completed the process. If the air doesn’t go out totally, you may have to consult your mechanic to find out why the power steering pump will not bleed air out of the system completely.
