Thanks T-Bird for the clarification! Resonator it is. lol OK, Lets recap. After having the power steering pump replaced and the steering rack replaced the fluid was still boiling due to a restriction in the line. My feeling was the only thing left was the High pressure line and the cooler as well as the low pressure line.
After logging on here I got a critique of dealers from Chipset, but nothing that helped in diagnoses.lol And then Tbird confirmed my suspicions. Thanks Tbird! I took the low pressure return line and transmissions line off and removed the cooler. I could blow through both by mouth easily, but still flushed them both out and then checked the low pressure return hose. Also good. That left the high pressure line w/ resonator.
Now I ordered a new line and installed it easily then connected all but the low pressure return line. I capped the power steering pump on the bottom, filled it with fluid and turning the car over without starting pumped fluid through the system with fresh Mercon V. Then Attached the return line refilled the pump and started the car. With front wheels on jacks I turned the wheel left and right until I was sure all air was removed. Everything is great and I have no idea why the HP line was restricted I could easily blow through the old one, but it had to have been the problem because all is well! My brother has been a Ford Tech for 25 years and never got a vehicle in yet with boiling power steering fluid and he works in Titusville, Florida. I've seen a lot of people asking about this problem all over the net, but no answers. I found my confirmation here! Thanks Ford Forums!
