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. 

Just joined the forum. Have a 2010 sel  and a 2011 Limited that i am in the middle of swapping a 2014 motor into. Fun stuff,its been a learning curve.
