Drained as much of the PS fluid that I could and filled with Type F ATF. I then turned the wheel back and forth from stop to stop until bubbles stopped coming up in the resevoir. I then ran the engine to warm it up and then connected the PS and ran it at about 750 RPM and turned the wheel back and forth a couple of times and shut off the engine. This is what the oil looked like. I assumed that this came from the remainder of the PS fluid in the system. I used a spoon and skimmed off the foam and repeated the process.
Finally after a few more tries the foaming stopped and the fluid looked nice and clear. There may be a small amount of PS fluid still in the system but, hopefully that won’t cause any problems. It is a bit darker that the photo shows as the camera used the flash. Topped it up and put on the lid. Keen to try it out but I have a couple more things to do before then: bleed the brakes and set the initial alignment. Then I’ll be able to take my first test drive. Progress is a bit slower now as it’s spring chore time as you all know.
