How to bleed air from power steering 02 kia optima

Yes,when foamy,indicates that you have a leak,which causes it to be foamy.Inspect pump for leaks,if none,follow hoses till you find leak.

Remove cap fill fluid to cold line turn wheels to left stop then right stop do this several times until fluid is no longer foamy. Must be done with cap off to allow air to escape system.

spray down pump and hoses with degreaser and wash off. After its dry, use recomended fluid to fill. Start engine and turn steering wheel all the way left, and all the way right a couple of times. This will blead the air from the system. Now shut off and check fluid. Make sure it is full. Now drive the car down the road and make turns, and drive it back and check fluid level. If its still foamy and not leaking fluid, your pump ma be bad.

Open the hood and check the level of the power-steering fluid by removing the power-steering reservoir cap. Add the correct fluid recommended in your owner's manual to bring the level up to the full mark. Be aware that fluid that looks foamy is an indication of air in the system. Replace the cap.
Locate the power-steering bleed valve on top of the steering box near the bottom of the engine bay. Follow the power-steering, high-pressure lines from the power-steering pump to the steering box if you have trouble locating it.
Push a 6-foot length of rubber hose onto the end of the bleed valve. Run the other end of the hose into a drain pan.
Start the engine. Loosen the bleed valve fitting slightly with an adjustable wrench in a counterclockwise direction. Turn the steering wheel all the way to its stop one way and then the other several times. Shut the engine off.
Close the bleed valve by tightening it with an adjustable wrench in a clockwise direction. Remove the power-steering reservoir cap, and add fluid to bring the level up to the full mark.
Observe the power-steering fluid that came out of the rubber hose into the drain pan. Repeat the above procedure if there are air bubbles in the fluid. Close the bleed valve and remove the rubber hose when there are no air bubbles in the fluid expelled from the bleed valve. Close the hood.

Is it full of power steering fluid ? How are the hose's high pressure and low pressure ? Did you bleed the air out after changing the pump ? There is no filter .
Verify power steering fluid level per operating specification. Refer to Checking and Adding Power Steering Fluid.
Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid aeration (pump noise/whining).
Verify the fluid level. Repeat the bleed procedure, if necessary.

power steering pump probably went out.. if you can easily get at the belt and are any kind of mechanically inclined, remove the drive belt to the p/s pump and then start the car if the noise is gone then its probably part of the power steering pump

if its been a week, there should no tbe any air. if its heavy, the rack could be bad, or weak pump????? any noises? air will usually cause a whiney noise, and there will be air whipped, foamy fluid in the pump. A pump pressure regulator could be stuck open, not allowing full pressure? I would have a shop diagnose it, tell them the history and see if they can find a cause.

if gets low definitely a leak foam is pump mixing fluid with air roar is pump cavitation check lines or pump for leak keep fluid at recommended level air bound unit can cause steering difficulty and or failure if need have trained mech look into problem

FIRST OF ALL YOU HAVE TO REMOVE POWER STEERING FLUID.USING A SUCTION GUN OR LARGE SYRINGE.REMOVE MUCH FLUID AS POSSIBLE.WHEN DONE REMOVING POWER STEERING FLUID.YOU NEED A INLINE WRENCH AND OPEN BOX END WRENCH TO REMOVE THE POWER STEERING HOSE.YOU HAVE TO REMOVE POWER STEERING LINE FROM THE RACK.UNDER THE CAR SAFELY RAISE AND SUPPORT VECHICLE. THEN REMOVE THE TIRE OR WHEEL.THEN REMOVE THE INNER FENDER SPLASH SHIELD.ITS GOING TO BE A TIGHT FIT AND HARD PLACE TO GET YOUR HAND TO REMOVE THE POWER STEERING LINE FROM BOTTOM.WHEN DONE.MAKE SURE NEW POWER STEERING HOSE OR LINE HAS NEW O RINGS.WHEN INSTALLING THE THE NEW STEERING HOSE.WHEN ALL IS DONE BLEED POWER STEERING SYSTEM. FILL UP POWER STEERING PUMP TO CORRECT FLUID LEVEL.THEN LET IT SET FOR 2 MINUTES UNDISTURBED.THEN START THE ENGINE RUN IT FOR 2 TO 3 SECONDS.ONLY CHECK THE RESERVOIR AND ADD MORE FLUID AS NECESSARY.REPEAT THE OPERATION UNTIL THE FLUID LEVEL REMAIN CONSTANT.NOW RAISE FRONT OF THE CAR UNTIL THE WHEELS CLEAR THE GROUND START THE ENGINE AND INCREASE THE SPEED TO ABOUT 1500 RPM.NOW TURN THE STEERING WHEEL GENTLY FROM STOP TO STOP CHECK THE FLUID LEVEL.LOWER THE VECHICLE TO THE GROUND WITH ENGINE STILL RUNNING MOVE THE CAR FORWARD SUFFICIENTY TO OBTAIN FULL RIGHT LOCK FOLLOWED BY FULL LEFT LOCK BUT DONT HOLD THE SREERING WHEEL FIRMLY AGAINST THE STOPS.RECHECK THE FLUID LEVEL IF THE FLUID IN THE RESERVOIR IS EXTREMELY FOAMY ALLOW THE CAR TO STAND FOR A FEW MINUTES.WITH ENGINE OFF.WHEN JOB IS FINISH. WARNING DONT DRIVE CAR ON ROAD IF YOUR FLUID STILL FOAMY OR POWER STEERING PUMP MAKE NOISES.REBLEED THE SYSTEM AND CHECK FLUID LEVEL AND CHECK FOR LEAKS.DONT DRIVE CAR UNTIL YOU START FEELING NORMAL STEERING.IF YOU HAVE TROUBLE DONT DRIVE.HAVE IT TOWED TO THE NEAREST GARAGE.

you have to bleed the power steering system. you have someone turn the wheels to the left while you watch the power steering fluid level adding as needed. than repeat turning the wheels to the right. and repeat until the noise seems to get quieter and you don't have to ad any more fluid.
