I need to drain power steering fluid and from what I can see, right where it goes into power steering cooler there is a low pressure clamp on the hose, would this drain the entire system with eng running?

Here is how I flushed my system... http://forum.mopar1973man.com/threads/1298-Power-Steering-Flush-on-a-3rd-Gen. Are you flushing it, or removing it for maintenance purposes?

Just changing fluid and top off with Amsoil ATF.

That thread should be all you need.

Talk about lost, let's make this simple, the line that comes off the bottom of the resoviar has a smaller line (return) coming from the brake boost which goes to the cooler. Take that line off raise front tires off ground and turn steering wheel back and fourth, add oil and do one more time?

Take one of the lines off at the cooler and drain the system, hook it back up. Then you can pull the line on the reservoir and put it into a container, add fluid to the system and turn the wheel a few times until the reservoir is dry, do that at least twice. Put the return line back on, top off the system and turn the wheel a few times. Then start and turn the wheel and pump the brakes, top off until its full.

Got it , Thanks
