Good afternoon Community I have. 2000 ford Taurus SE 24 Valve DOHC V6 with only 55K miles approximately. My problem is with the power steering. I fill up the reservoir then bleed the line of air using the steering wheel method 20 times like YouTube Mechanic suggested. What happens is when I turn off the ignition then the fluid bubbles up and out through the top of the reservoir. I’ve just found out that this vehicle used Mercon V fluid for both the transmission as well as for the power steering system too. Is this a symptom of air getting into the line? Also I’ve had to use a generic hose not the correct hose for the line coming off of the top of the reservoir. The problem with the oem hose is it’s a discontinued part by ford. I’ve looked around in local junk yards and no luck not even one ford Taurus around to take oem parts from. Any suggestions would help please

One of your return lines is sucking air into the system, or the pump is. The pump pressurizes the fluid & air, & then the air is rushing back to the reservoir.
I need an oem hose because I’m missing the one on the top coming off of the power steering reservoir. It’s the thick looking hose on the left side of the picture. Is that a possible return line? It’s not the original hose because apparently it’s not made by ford anymore per my local ford dealership service department manager.
This happens when you turn the car OFF or ON ? If "on", like bullwinkle says, it's sucking air in - very common on Hondas, in my experience, and presumably other models. If when it's "off", I'm lost as to why it would do that.
It Happens when I turn the car off, yes
Press hard on the thick hose. If it compresses some, then it is a return line. The high pressure hose does not compress. Air cannot get into the HP hose when in operation.
The plastic reservoir is not going to have pump pressure on it. Large hose should be the supply to the pump and the only line with negative pressure. Check the clamps for tightness on either end and make sure that there is no obstruction like a dropped foil seal in the reservoir. Worst case scenario is that the pump is drawing air past the shaft seal. No matter what you are working on, always check the easy stuff first.
The return hose is the reservoir uppermost hose in my experience. And yes, it is not pressurized so it can be soft as compared to the pressure line.
