I am going to see how much more volume the new one is compared to the old one while it is apart, so I can figure the increase and still be able to flush the cooling system the way I do now. Flush with distilled water until clear, put in however much coolant it needs for the mix I want and then top it up with water. I am not tracking it, so I am not too worried about cheaping out and not getting the cross flow. I am fairly sure it will be a significant increase in capacity, it looks freakin' huge.

The Montero Sport has over 10 quarts in its cooling system, according to the manual, takes a fair amount of distilled water to flush that baby out. Gallon of Prestone gets me to 40% coolant, which is plenty for my purposes. Trans fluid was fairly dark, but did not smell burned and looked clean. Probably placebo, but it seems to shift smoother.
