I Have A 1967 Chevelle With A Saginaw Power Steering Pump. What Kind Of Fluid Should I Use Atf Or

Most modern power steering system has a pressure relief built into it. Most are in the cap. The fluid will expand with heat and the pressure relief will let it over flow out of the system. Then you have a mess. That’s it. No harm done. To the system at least, but not good for the environment.

So you're not gonna like my answer ... I'm not sure why you can't replace the pump assembly. In the end it might be easier. Either way you'd have to order parts, spend money, so why not simply replace the pump? It's available, online, at RockAuto.com for about $50 rebuilt and I'm sure you can score one at your local auto parts store. The reservoir, hoses and other parts are also available. Or you could hit a local salvage yard and get one for even less. I believe you'd need to get a special tool to remove the pulley but many chain auto parts stores can let you borrow one for free. You see the problem with just yanking the pump is the steering box. The steering box is a power steering box. And, yes, it would probably work without the hydraualic pressure provided by the power steering pump but not for long. The hydraulic fluid, among other things, is what lubricates the the internal mechanisms in the steering box. If you don't have fluid running through the box then eventually things can get "sticky" or just seize up. And you can't just put oil in the box and close off the hose lines because the box is designed to have fluid flowing through it; you'd stand a good chance of hydraulically locking the steering gear. None of which is good. Brakes and steering are two systems on any vehicle I, personally, want to have working at 100%. But that's me ...I'm kinda funny that way. Maybe you have good life insurance.Manual steering boxes have grease in them to keep things lubed ...so you'd have to buy a manual steering box to replace what you have now. Or at least I would ...you can choose to do whatever but I wouldn't trust running a power steering box without the system fully operational. You might be able to find a manual box at a salvage yard.  To bypass the pump you'd need to find the routing for the serpentine belt used on a non-power steering 94 Ranger. You can find that information online. You can also find what belt to use on non-power steering equipped Rangers. You might need an idler pulley ...again you can find that out by doing some research online.My advice? Replace the pump. You'll be much better off.
