Power Steering Sauce...Pre-'68 Era


Hi, all. Thanks again for the feedback on my last inquiry. It all worked out as a result of your replies. Now I'm about to change out my power steering pump ( that leaks like a colander ). I've got the new pump sitting here already ( Cardone rebuilt ) and it's ready to go. Did some research about what fluid to use and I found varying suggestions across the internet. The 1965 Turquoise Beaumont Bible says to use "special fluid, part number 5723684 ", but 51 years later we can doubt that GM would still have that part number attached to the original product or even have the fluid at all. The "top-up" recommendation of the day was transmission fluid "type 2".

Since I'm installing a fresh pump and will be flushing the system completely, some ( most )  say the best way to go is to just use GM power steering fluid, period...and not to use the ATF at all.

What do you '64 to '67 guys have to say on the subject ?  What's my best way to go ?

Thanks again,

Gar

I personnally have always used auto transmission fluid. Some disagree. See this thread where carl mentions flashpoint of ATF and power sterring fluid.

Always always always  Automatic Transmission Fluid, Dextron or similar.  Use the same stuff in your powerglide.

Well, I'm sure there are guys on here that have more knowledge than I do but this is my experience.  I worked for about 4 years at the last remaining GM plant that manufactured the steering gears, pumps and even power steering hoses.  At that time I believe the primary use of these units were service parts and trucks.  The remainder of our plant locations were building rack and pinion assemblies and half shafts for front wheel drive.  The complex was for years and years know as Saginaw Steering Gear.  During my tenure we were known as Saginaw Division of GM, Saginaw Steering Systems and finally Delphi Steering Systems.

In 1990 I asked the guys in the plant to rebuild the power steering gear on my 1969 Nova SS I had restored in 1985.  I got the rebuilt pump back just prior to leaving for a Super Chevy Show in Atlanta, Georgia.  The guys were nice enough to include a new set of power steering hoses so I installed everything, put the car on my trailer and headed for Atlanta about 1200 miles away.  Upon unloading the car and driving it around the parking lot, I found I had a power steering pump leak.  Long story short, I spent an entire day trying to find the leak.  When I could not find it, I drove the car into a show on Sat. and then drove it 30 miles or so to the Super Chevy Show on Sun. with the belt removed from the pump (manual steering).  During the day of exploring for the leak, I read all the original literature I had and made a couple calls to sources back home for advice.  I was told to use Type F ATF which at the time was used by Ford for all their automatic trans.  I bought a couple quarts, not knowing now much was going to end up on the ground.

When I returned home to Michigan, I investigated all the parts a little closer than I could in the parking lot of the Marriott hotel in Atlanta.  My new power steering hose on the pressure side had been built with a taller nut than the threads on my gear.  Therefore when I tightened the hose 100% on the top of the gear, the flared fitting on the end of the hose was not entirely seated on the fitting.  I then machined about 3/8" off the nut and it worked perfect.

Bottom line, I would use Type F ATF if it is available.  As a result of the above experience, the guys in the shop gave me a handfull of brass "compression nuts" used in the fittings on the top of GM gears.  I still have them and have never disassembled a gear.  Prior to finding the leak, they gave these to me in case one was cracked on my gear and causing the leak.

Sorry for the lengthy post but at my age, I enjoy sharing my knowledge and experiences with anyone listening.

Thanks for the responses, guys. My rebuilt pump was originally designed to use ATF, the filler cap says to use ATF, and the replies here support that for the most part as well... so I'll use what I used before : ATF.
( Dexron III equivalent - Mobil ATF DM ). The same stuff my Powerglide drinks.

Forespeed : thanks for the note on unexpected sources for leaks.

Okay - So 2 new entries on this now. Thanks GLHS60 and 427carl. At least all of you responding agree on using ATF - as opposed to PSF in the mid-sixties GM power steering systems. Now though, it seems there are 3 posts suggesting ATF Type F, and one suggesting Dexron as a few others have done off-site. I'm not about to argue with Saginaw about the right fluid to fill my Saginaw system with. What bothers though me is the variance in the answers to the question across the web. From what I've read, original Dexron was apparently introduced by GM in '68, it turned out not to be the heavenly fluid it was meant to be, was replaced by Dexron II, then later Dexron III. All of these Dexron versions are supposed to be backward compatible. So I guess the new question should be :

"Type F Users & Dexron Equivalent Users Alike... Speak Out Together, Ya'll : Who's Had No Steering Pump Problems For Years On End Using Your Chosen Juice ? "

GM power steering fluid here.

I've never replaced a power steering pump on anything I own and I'm 58. I still say it's worth using, and safer too (because of the fire hazard)

And as the disclaimer always says, "your experience may vary".

Finally - a vote for PSF. Thanks, Carl. There's one reply to the new question. ( I'm 59 myself, btw, but I've never had a 51-year-old Beaumont before ).

To me the most convincing argument to use it is the part about reducing the chance of a fire if the pressure hose would burst. And that's not an uncommon event, it happens.

Yup. ATF lights up nicely. I've been incinerating all the damned used diapers I've had to wrap around that old pump for the last 6 months just to drive it without spraying the stuff in a circle pattern all over under my hood.
