I am going to be installing an '02 Explorer engine and '01 Cobra radiator in my '95 Cougar. I don't want to use the traditional green coolant, because of the sediment in my overflow tank, and the new engine with less than 1000 miles already has "crystals" forming in a few passageways. I was going to use DexCool (prestone), but I have heard some horror stories about it. Then I found the Zerex G-05, and it seems to be pretty good stuff, So I think I'm going to go with that (It's listed as meeting or exceeding Ford's Spec for the Explorer's coolant). The question is, should I mix it 50/50 or . I always thought that a mixture (50/50 or so) raised the boil over temp of the coolant, but also the freeze point. The Zerex, however, has a 70/30 (70% A/F) freeze point of -90F, and a boil point of 277F, and a 50/50 of -34F and 265F. Granted, my car will more than likely never see -90 (and hopefully nothing over 215 or so), I would like as much boil over protection as possible.
What is everyone's sugestion and opinion on the G-05?
Thanks
