Power steering fluid

Post by Timd »

Ok so I ordered my new pump and my question is, on these new pumps do I still run type F in it or just regular fluid?

Thanks

Since the first question is answered... i hope this isn't considered a hijack but...
does anyone know if the type F is necessary for the pump or the box or both?
For example, if you change the pump to a saginaw style pump which specs dextron III do you switch power steering fluid for the pump of stay F for the box? What if you mix the two? Oh man...

Excellent question... :clap:

In that case, I'd spec the PS (hydraulic) fluid to the pump rather than the steering gear since it is the pump producing the pressure.

I've been using Mercon V and/or Mercon LV on both the power steering pump and transmission for about 7 years now with no problems.

Mine was leaking so bad I put 5w30 in it. I didn't have the money to fix it and you got to do what you got to do to get by. That was ten years ago. I was young and poor. I think I eventually had to use 15w40. I ran it like that for about three years before I got rid of it. Didn't want to steer very well when cold but once it warmed up it was fine. Those things are tuff. Wouldn't recommend it though lol.

I use International Harvester "Hy-Tran" in leaking power steering. Not sure what is in the product but it seems to bring the old seals back to life and works very well in any weather. I put 20 gallons of hydraulic oil, Type F, Mercon 5 you name it through the power steering of my old 930 Case tractor in the last 25 years and I put 1 quart of Hy-Tran in it 2 years ago and it is still going strong. But Type F is for Ford's. I run it in my FMX's and Borg Warners.

A game with words? I thought it was kind of funny once I figured it out. The dipstick for the power steering pump in my '70 Mercury calls for Type F. As far as I know, it's still the original pump. The power steering pump in my '69 Bump says "Use Approved Fluid" on the dipstick. That pump came from a '76 Dentside. When I did a bit of research, it turns out that the "approved fluid" for that pump is Type F too. It makes you wonder why they didn't just say so. :lol:
