Urgent help request! Power steering fluid foaming.

[vvs75]

Hi guys, tried to flush my steering fluid, did everything per instructions below:


Replacing the power steering fluid is
easy in the 4runner. Here are the steps although this probably isn't detailed enough to stand alone:

0) Jack up front wheels off ground,
1) Aspirate reservoir with hand pump
2) Remove pump return hose (catching the little bit remaining in reservoir) and attach an 3/8" id extension hose using a double barbed connector leading to a 1/2 gallon milk jug.
3) Refill reservoir with new ATF.
4) Run engine for several seconds until reservoir is down close to empty to purge the PS pump. (need a second person for this)
5) Refill reservoir and turn steering (engine off) from lock to lock to purge rack, until the reservoir is close to empty again.
6) Repeat from step 3 again. (You'll about 2 liters of ATF to do all of this.)
6) Replace lower hose and top off reservoir.

My fluid coming as foam without end wasted two gallons already. Its looks like air got to the system.
How to get rid of it if this the case? If not what to do?
I am leaving now for about two hours but when I come back I must to fix the problem ASAP.

Its looks like I had original fluid there, then I added Advanced Parts Dextron II, III
Please help!!!
Many thanks!

I did not have a problem when I did mine. Continue turning the steering wheel lock to lock with the engine running. Only let it run for a short period and recheck the fluid level. Mine only took a quart and a half to purge all the old fluid. Does it feel like the power steering is working at all?

Edit: still no go

Ok I Jacked up front wheels off ground and still same thing. It empted my extension tank literally within one second or less and throw red foam from the return hose. I can’t even get to the point where I need to turn the wheel. Continuin pouring ATF in result in more foam frome the hose.

If somebody who have few minutes and know what to do, care to help me over the phone to help me figure out what I am doing wrong. I really need to fix it ASAP. PLEASE!

Maybe I am misunderstanding you, but when I ran the engine and turned the wheels lock to lock I had all the hoses reconnected and the reservoir full. I do not understand where you are seeing the foam. Just hook everything back up, fill the reservoir, turn the wheels lock to lock, start the engine and check the fluid level. Repeat filling and turning lock to lock to bleed all the air and make sure it feels like it should.

Thank you for the help anyway.

That’s exactly what I did in the end. Reconnected returned hose and topped the fluid.

The foam was coming from pump return hose. Fresh fluid going to the cylinder and foam from the back hose. That is how I used to flush all my cars.
If you just suck out old fluid and top it with new it would be refreshing.

I still don't get it how somebody could flush it.

I did mine a little different. I removed the hose up by the powersteering fluid cooler in front of the radiator and put on a hose to reach into a bucket. With the wheels off the ground I turned the steering wheel back and forth till no more fluid came out (engine off). I then reattached the hose and filled the reservoir and repeated the process 3 or 4 times. When the fluid was all clean I reattached the hose filled the reservoir and then started the engine and worked the wheel lock to lock to get the air out refilling the reservoir as needed. It sounds like you got yours flushed pretty good. It does get frustrating at times.
