If the the rod moves only a little, it's still attached to the tensioner body. Don't move it any more.
I don't understand the question "Where do i lift the tensioner screw to the right?"
If the rod is loose enough to wiggle, and the tensioner is not touching the bracket, then that's enough.
Turn your attention to the tensioner pulley. You should be able to move it by hand at this point.
... Conversely, my two left hands replaced the tensioner assembly without touching the power steering pump.
