I pulled the old power steering pump to replace it and when I disconnected the hoses the fluid coming out looked like chocolate milk. If I remember the recipe correctly you add water to oil and pump vigorously. Not very good for things. So the question is how to deal with it. I figured I should flush the system before installing the new pump, but how?

BTW, the steering felt fine before I started the rebuild process, except for a little play.

 

If it was me, and it had a C-II pump I would not replace it. I would go find a Econoline with a windsor engine and grab that bracket with the saginaw pump buy a hose flush the system and be done with it.
I fought for years draining my system every year flushing and filling(with mercon V) until driving down the road the pump just had enough and gave no assist(truck sits on 31s nothing special). My other F4(roller 351w) engine came from a E250 with 190k, I took that bracket bought a hose it has been in place since flawlessly, quietly, and happily operating.

my 2 cents,

Sounds like a good idea... if I hadn't already bought and started installing a replacement pump. Oh well, maybe if I put in a rebuilt engine in a another year or two.

How would you recommend flushing out the existing hoses and steering box?

 

I have a plan on flushing and would like opinions.

I was thinking that I'd install the new pump, hook up only the pressure line, and leave the cap on the reservoir fitting on the pump. Then I could put fresh fluid in the pump reservoir and turn the pulley by hand to circulate the fluid catching what comes out the return line in a bucket for disposal. I'd keep doing that until the fluid coming back the return line was clear. Does that sound like a reasonable approach?
