 I have had plenty of Explorers but my 2006 limited was final purchase for awhile and the plan was to "drive it till the wheels fall off,"  I am not a heavy driver.  My commute to work is about 20 miles total.  I took the Explorer in for service after the second year of owning it. I was told I had "cracked hoses" and that was why my fluids leaked.  I mentioned all the complaints that I saw on the internet with radiators, the ford garage did not know of any "problems." They fixed it and then the next summer it was leaking again.  I was told that was "normal" in the summer and was talked out of making an appointment.  Just after 36,000 miles I was then told my radiator was shot.
