NOTE: During air bleeding, fill fluid so that its level is always higher than the MIN line on the oil reservoir. CAUTION: If the air bleeding is performed by operating the engine, air will break into small particles and melt into fluid. Be sure to perform the air bleeding while cranking the engine. Before servicing the vehicle, refer to the Precautions section. Jack up the front wheels and support them. Disconnect the ignition coil connector. Turn the steering wheel all the way to the left and right five or six times while using the starter motor to crank the engine intermittently several times (for 15 to 20 seconds). Connect the ignition coil. Start the engine. Turn the steering wheel to the left and right until there are no air bubbles in the oil reservoir. Confirm that the fluid is not milky, and that the level is between the high and low dipstick marks. Confirm that there is very little change in the fluid level when the steering wheel is turned left and right. Confirm that the change in the fluid level is no more than 5 mm (0.2 inch) when the engine is stopped and when it is running. If the fluid level rises suddenly after the engine is stopped, the air has not been completely bled. CAUTION: If air bleeding is not complete, there will be abnormal noises from the pump and the flow-control valve, and this condition could cause reduce the life of the power steering components. If the change of the fluid level is 5 mm (0.2 inch) or more, the air has not been completely bled from the system. The air bleeding procedure must be repeated.

Need your make, model & year. Newer cars don't even have PS pumps sometimes, they went electric. But an example on a Honda Accord would be: 1. drain PS reservoir by removing hose connected to the PS pump 2. Loosen the large nut on the pulley 3. release tension on belt with a ratchet & socket, remove belt 4. ratchet off the 12mm bolts mounting it to the engine 5. Remove hoses 6. (optional) flush PS fluid from steering rack 7. install new pump & fill 8. purge bubble by rotating the steering wheel lock-to-lock 9. top off with appropriate PS fluid
