what is it lately with these guys coming on here, have like 0-20 posts to their name (not saying post count means more experience, but generally, you have a little more) and saying stupid crap that is absolutely wrong...it angers me. kinda like that guy that said our transfer cases weren't shift-on-the-fly....

 

Yeah, newbs these days. Funny, because my Mustangs manual says Motorcraft power steering fluid or Auto transmission fluid type F. Just the Dodges are touchey?

 

it all depends on how the pump was designed. if the pump was designed to take a certain type of fluid, you should use that fluid (i.e. ours). or theres that case like your mustang, where atf would work instead.

 

Just to put an end to this thread, look at the back label of any power steering container. It will say that it is equivalent to Chrysler 5931. So just use power steering fluid...go figure.

 

I know regular Valvoline power steering fluid is equivilent to MS 5931.

 

I have been having an ongoing problem here as well. I initially changed out my PS pump due to leaking out the lid and gunky gooey built up inside the pump. The leaking from the lid immediately got worse leading me to changing the lines, thoroughly cleaning the cooler and putting a new PS gear box in. Still gushing out of the cap even at idle. Its not over filled. I used Valvoline PS fluid as there are. No specified fluid types I could find. Im going nuts here. This is FAR from my first power steering pump/gear box swap. What am I missing???

 

Did you bleed the system with the front wheels off the ground?

 

Not off the ground no. I have never needed to do that with other vehicles. Is it that critical?

 

I prefer to do it that way, so I am not grinding a flat spot on the tire...... it's also less stress on the pump/steering gear, while there isn't much fluid in it. (it's also easier on the arms... power steering without the power makes for a great deal of exercise.....) Being off the ground reduces pressures required to make things happen.... so, you get less undesired results. (like blowing fluid out of the pump. )

 

Oh I understand losing fluid during the bleeding process. I mean this goes on forever after. Even if I let the pump get below the full cold line, first time I turn while hot or cold... Gush. Its way worse if I get on the gas hard.
