Power Steering Fluid

Posted by Packard 1948 On 2015/8/23 14:44:50

I just installed PS in a 1949 Packard.

The modified system uses a 1953 Chrysler 6V Generator that has a PS Pump attached to the back of it and the other end of the hoses is a Monroe external hydraulic actuator that is installed in lieu of the center link and this is the unit that the 1955 Packard used for PS.

The Chrysler manual specified SAE-10W however the Packard manual specifies "Ultramatic" fluid (also called Type A fluid however some say Type F can be used as a replacement).


Does anyone know what kind of fluid I should use???I was reading the PS Training Manual and it says to use Type A Automatic Transmission Fluid.

I had already installed regular "Power Steering Fluid" in the system. Is this an OK practice or should I drain it all and replace with ATF...and if so what type of ATF (Dextron or Type F)?

THANKS!!!
