New member here so take my post with a grain of salt. We own a 2010 with 175,000 on it. Never done a thing to it coolant-wise.(however I'm gonna flush and fill now!) It has the green in it. However I just bought a 2011 with the orange in it that has a blown motor at 71,000 miles.( I bought it this way) I am an advocate of over maintaining as coolant changes are much cheaper than engines. I am swapping a 2014 engine into the 2011 and tried to post pics earlier but I think they are too big. I have a friend who is a Master Ford tech an he told me that they switched to the Orange coolant to eliminate "hot spots" in the engine block. He says BS on the reasoning.
