So I was stumbling around under the hood this afternoon and was looking at the coolant in the expansion tank. Stuck a paper towel in there to see what color the coolant was and it came out yellow/green. Everywhere I have looked indicates the 2011 Armada should have blue Asian spec coolant. Can anybody give any insight on what coolant the vehicle should have? I'm not necessarily worried about what's in there, but if I ever need to top off the coolant that makes that a little more complicated.
