New power steering pump, big problem!

Sounds like the pump is working against a dead blockage. Are you getting any power assist out of it?
A pump will get real hot real quick if it is pumping full pressure against a blockage, and the bypass valve inside the pump will make a lot of moaning noise.

Well that sounds like what it could be. So flushing as instructed will clear this blockage? If not, how can I find where the blockage is?
Thanks fellas!

The original pump had started losing its fluid through through the front of the pump, I have no idea how but it would leak around the shaft. I didnt realize it was leaking until it started to screech when turning sharply. It quickly got worse and the fluid level kept dropping. Finally I found where it was leaking and decided to replace it as well as the lines. I never knew anything about the need to bleed the system, but I'm trying to learn this stuff. I guess this will be a good learning experience.
Could this blockage be in the new pump itself or what? Any ideas on on to check if that is truly what is going on?
Thanks,
Shane

I have cutaway drawings of the filter in their master catalog.
The 58964 filter has 5/16" inlet and outlet ports and is the same filter found in the Ford part.
A similar filter with larger 7/16" inlet and outlet ports is number 58953.

Well, if the steering box was working fine before, and the new hoses aren't collapsed or kinked somehow, I would think the pressure valve in the pump is stuck closed and the extra pressure the pump builds up is not being bypassed like it should. This will cause excessive heat and noise.
You still haven't said if you are getting any power assist, so I will assume that you are, so the pump is making pressure to the box, but isn't bleeding off the extra pressure.

I honestly dont know if I am or not. I backed it out of the shop and drove about 10 feet to where it is sitting now. The noise and resistance in the steering was incredible. I could maybe say at times there was power assist-where the resistance let up and it could actually turn the wheels.
Another thing to note is that even though the old pump was leaking and making noise it turned and steered perfectly...this has basically turned into a nightmare.

It seems clear to me that you should consider returning the pump to AZ and start all over with your newfound knowledge.
Since the pump from AZ is making that much noise and getting that hot, it is most likely already damaged; either from the reman or from failing to properly bleed the air from the system.
Save some diagnostic headaches and start fresh.

That is clearly a bad pump.
Eric- its actually a metal screen that is magnetized (similar to most transmission filters)... media would be useless in a filter that small flowing that much fluid.

Ok, tomorrow I will finally have time to get that pump off. I have already ordered a new (non-reman) from NAPA so that will give me a fresh start.
I read the FAQ on how to bleed the lines and have a question. What is the best way to plug the return outlet? Also, when I have someone turn the wheel side to side should the tires be off the ground? The AZ guy said they should be up but its not mentioned in the FAQ. On the filter, do I just cut out the appropriate amount of the rubber hose and put it in-line where the cut is made?
Thanks for all the help!

To plug the return outlet, take the old hose (if you still have it) and cut it off where the metal meets the rubber. Plug or cap that line to make it sealed.
It is preferred to have the front wheels slightly off the ground when maneuvering the wheels fully side to side. This will eliminate any unnecessary stress from or to the steering system while servicing the pump.

Why would you say that! You are completely wrong again, please pay attention. I have two pages of information with operational characteristics, cutaway drawings, and descriptions of all the parts in the #58964 filter to look at. The magnet element is a ceramic disk, the filter is a standard paper element with a steel core support. The magnet is still effective even if the filter element goes into bypass. Flow rate is small on transmissions and power steering systems. The filter is designed for 2-3GPM max flow rate.
