2005 Ford Escape, 2.3 litre 4Cly. I am going to change the power steering fluid myself to Mercon V. I have the link for the fluid change procedure and also I have the Ford Workshop Manuals, but I am still not sure which line is the return line to the power steering fluid reservoir. Is it the large (maybe 3/4") line that goes to the side of the reservoir or the smaller (maybe 3/8") line that goes to the bottom of the reservoir? ???
