POwer steering question
I am finishing up the power steering swap. During the clean up, changing of soft parts and installation I have managed to loose most if not all of the fluid in the retrofitted parts. My "POS" Chilton’s manual suggests type F automatic transmission fluid. I guess this is OK but it does beg the question "Why do they sell power steering fluid". Also I can't seem to find anything in the manual about replacing all of the fluid. Is it like a brake system? Do you need to bleed it some how? If so, what’s the process. Or do you just fill the pump, cycle the steering and fill again until you reach the mark?

I have that same Chiltons book. But, my Haynes book says the same thing. I read somewhere a long time ago the reason Ford required the Type F fluid. I just can't remember what that was exactly anymore.
As for filling it, just get it to level on the stick, start the truck and turn the wheel to the steering stops in each direction a couple of times and that will bleed the air from the system. Get the engine up to temp. and check your level. Don't over fill though.

The dipstick on my power steering unit says to use ATF, and for that year, we're talking Type F. Although, that's getting difficult to find. I've been using Type FA which of course is suitable replacement.
I just put a new power steering unit and pump into my truck. I used Type FA fluid putting in about 4 oz at a time cycling steering until the stick said it was full.
Any air will naturally bleed itself out as the fluid recirculates like your engine but unlike a brake system.

Sometimes the ps pump has a problem purging itself. What I do is pull a vacuum on the filler pipe with one of those miti-vacs while idling. You can hear the pump make some groaning sounds, only takes a minute or so.

Is there any problem with using the new synthetic pwr steering fluids (Valvoline)? I just put a rebuilt box and pump in my truck and that what I used. Pump does seem to whine a good bit and the air is definitely out so thats not causing the noise. Thoughts?
Thanks.
Thanks.

Are you sure that the whine is not the belt?
I'm not a proponent of belt dressing (in the spray can.) I feel that if you're belt is slipping then you're belt is bad, the pulleys are dirty or the tension isn't right...
but as an experiment, you could spray it on and see if the whine changes.

A little spritz of WD40 will quiet the belt long enough for troubleshooting. Less is better, you don't want a roostertail spraying an oily line across the engine compartment. Little trick we used to use in the shop.

For the ps, power steering fluid or Type F both will work. For an original tranny you still need to use Type F. If it has been rebuilt in the last 10-15 years then the clutches will have the later style frictions on them and you can use the latest Dexron III fluid.
