OK to run a power steering pump with no fluid?

My steering is leaking pretty badly and I want to get the Jeep together before I tear into another project. The power steering pump is dry now. Is it OK to run the engine with it dry? How about drive? I don't want to damage the pump, but I also dont want to continually fill it while most of the time it is sitting still.

Is the pump itself leaking, or just one of the hoses?

I think it is the steering box. The lines don't look great, but appears to be leaking from the box itself. I haven't been able to drive the Jeep yet, although I was able to move it 20 feet in 1st and Reverse.

I do plan to eventually replace with H1 box if it is indeed toast, and install new lines, but I'm 8k into a non-assembled and unpainted Jeep. Need to draw a line.

Well, if it's just the box leaking, and you can deal with no power steering, you can loop the high pressure line back to the return side of the pump, creating a closed loop at the pump. Then stick just enough fluid in the pump to keep it from burning up.

That's what I did when I dyno tested mine, since the dyno machine didn't have any provisions for the PS pump. I made the "loop" out of an old PS line I had laying around.

As for driving it this way, that's your call.

Good luck,

Matt
