2001 Sedan Power steering problem

Alrighty started off with a reman pump from advance and got it all put on. Hooked up the high pressure and return lines. Checked out no leaks. Fill the resoiver with fluid and started the car shut back off and filled with a little more. Started turning the wheels and got a kinda squealing/growling sound coming from the pump. Got all the air bubbles out and put the cap back on. Then shut the car off. But when we did this the power steering pump spit like a geyser. What is going on. Is it the pump or could the high pressure line be bad.

TIA Nolan.

I seem to remember a few others having a similar problem recently. Try searching the forum. I think "high pressure" may be a good keyword search.

I tried following the last ones recently and it didn't seem particularly clear what solved it. Has anyone heard of the check valve on them giving problems? Off hand, I'd guess you still have air possibly trapped in the system, or, if you have a filter or filter screen in the system or reservoir, you need to be sure it is not dirty or plugged. Did you do a full fluid flush and exchange? Maybe some debris became stuck in any filter you might have, blocking the flow till it let go. Did the fluid squirt out the breather hole in the top of the reservoir cap? How high is the fluid in it? Is it too high? You may need to elevate the front of the car considerably to help work any more air bubbles out. I'd not have the reservoir very full to avoid more fluid jumping out. I would also be sure you get all that fluid good and dried off, especially your paint and belts. Some here say it could make a belt good bad prematurley, even when wiping it down.

I suspect the fluid is bursting out because trapped air bubbles that are under pressure are expanding explosively when they return to regular air pressure. Off hand I don't recall exactly, but the volume change that air does when going to and from high and normal air pressure is quite significant. Considering that the operating pressure of the power steering pump could be a few hundred psi or more, the air could easily be compressed ten times its original size. So, when that thing comes barreling out of the return line, it's going to blast out ten times bigger than what it was compressed to when it comes out! Quack, Quack, DUCK! :D

Could I have a problem with the high pressure line. Or is the filter clogged on the low pressure line. Where is the low pressure line by the way.

Would that be a never mind? What progress have you made? Generally, the high pressure line leaves the pump as a metal line or a heavy duty rubber hose with crimped on ends that is screwed into or held by a flare nut. The return, low pressure line tends to be a lighter duty rubber hose and connects to the lower part of the reservoir often with just a hose clamp. Off hand, I don't know of any common problems that occur with the high pressure line, but I don't know it all to say there aren't.

Tryed bleeding out the system till we saw no bubbles. Then we put the cap on. We took the car for a little drive. We got back home. Took the cap off spit a couple more bubbles. Shut the car off and the resivoir spit up like crazy again. As soon as you start the car again, it sucks the remaining fluid in to way below where it is suppose to be and you have to fill it up more.

I don't know. The only thing I can find wrong in your story is starting it up with the fluid very low ( following the psp spitting a lot out) which could possibly reintroduce more air into the system. Is there any chance there may be a pin hole leak in any of the low pressure lines. I can't remember if the cooling loop is high or low pressure, but if it is low, that is where I'd look first expecting to see seapage and also the return line, especially where it connects to the pump.
