With a hobby syringe, and a length of hose attached to it. Run the car around the block with the new fluid in which will cycle the old stuff that's still in the system.
Then come back and drain it again. I also use the syringe to suck old brake fluid from the reservoir.

 

The reason why you would need to flush the system would be if there is a leak in a line, pump or rack which will then need repaired. Is your fluid dark and full of contamination? Low level when hot?

To flush and do an extensive check of the system, have a helper with you and disconnect the hose leading onto the resevoir and put the end of the hose into a empty container. jack up the front of the car and put on stands making sure the front wheels have plenty of travel. Start the car and start rocking the steering wheel back and forth. Have the helper add new fluid into the resevoir and continue until clean fluid starts coming out the hose into your container. Turn off the car. Replace the hose onto the resevoir and top off. Start the car and rock the steering wheel again through a number of cycles. Check for leaks around the pump housing and where the fluid lines go into the rack. Pay attention to any resistance or binding in the steering wheel and listen for groaning, grinding, or clicking noises from the pump and rack.

If the rack is leaking but no binding or noises are evident, it may just need the seals replaced.

 

69s route sounds like gold, but scotts more technical , the car parks in the same spot all the time, and i`ve yet to see any spots on the concrete. im going to try 69s route first since i cant get the car out the garage(snowd in) and see what happens, cant jack up the car either to turn the wheel freely

aside from this how far you think i`d get with a blow torch to melt snow away?

 

sucked it out, heres a pic for your pleasures, guess it never was flushed

That has a reddish look like automatic transmission fluid. Old p.s. systems used to be able to use tranny fluid, but you want to be sure to use designated power steering fluid only. I'll bet a previous owner with an old school mind set put the wrong stuff in. With that in mind, you might want to eventually (sooner than later) flush the system to get all the old stuff out.

 

this pic looks kinda red (cell phone) but that stuff was dark dark brown, the moan is very minimal and when i pull the cap the color of it is more clear than dark now, i think in a week or so i`ll do it again to get more of that crap stuff out, didnt do it today since i only had one bottle of ps fluid, but thank you both .

 

Alrighty then. From here the pic makes it look like dirty tranny fluid.
