Ford used green conventional coolant through 2001.
In 2002 they switched to the G-05 formula used by Mercedes, Chrysler, and several European marques.
The G-05 is longer lived and a bit less abrasive than the green.
I know that's probably the "book" date, but my parents 2000 Expedition came with G05 in it. So I think there were some early adoptions.
