Bleeding power steering pump

Am I going about this wrong? I have a new Delphi pump, new HB and new cooler so I wanted to prime it before I started it so I wouldn’t have to worry about the pump running dry. I’ll be starting the engine for the first time as well so I didn’t want to focus on the pump. This is with my battery impact. I can’t get fluid to start flowing. Am I doing something wrong?

I just filled it and fired it up. I think I refilled it 3 times to where it stayed full. I still haven't taken the time to cue the wheel to bleed it.

I was having a heck of a time getting my Saginaw pump to prime. I was using my cordless drill as well. I put a plug in the output line and tried and couldn't get it to prime. Took out the pressure relief valve that is under the output side fitting and using a small magnet worked it back and forth to make sure there wasn't anything causing it to stick. I thought I felt it sticking a little bit so after I worked it a bit , it felt like it was moving good so put it back together and continued rotating it with the drill and it primed up. Just get ready for it because being deadheaded it will come to a stop pretty quick. Hooked all the lines back up and it primed right up. Ken

I just filled it up, jack the front wheels off the ground, (with the motor off) cranked the steering wheel back and forth 20 times, disable the ignition and crank the starter for 5 seconds, all while verifying the reservoir was full. It was good to go after that. No need to run the engine to get the system pretty well primed.

Hi, why not start the engine and break it in with the power steering belt removed? Good luck

I could do that if I purchase a shorter belt. I figured the drill would do the same as starting it so I gave it a try.

That is what I did the last time and I'm sure that is what I'll do again. I was trying to save myself some time and the potential for running the pump dry while I start the engine for the first time.

I don't understand why using the drill is not circulating the fluid.

Is the drill set for the correct direction? I dont know which way the delfi pump turns, clockwise or counterclockwise but that may be your problem

This is the best way to bleed all the air out of the steering system. It takes a long time. If the fluid level drops when you start it up, then you still have air in the system.

Great video and I’ll be giving that a shot. I was more concerned about the pump not moving fluid with the impact spinning it.
