DEX-COOL will probably fine in your Ford, though Ford's made noises in the past that the stuff attacks gasket materials. (Too many people have posted excellent results with DEX-COOL in their Fords, so I'm not buying that argument, but be aware of it.) Ford's factory-fill these days is an amber-dyed G-05. Zerex G-05* is chemically the same - just dyed a harder-to-see amber once diluted down. If you use either long-life product, you should be good for at least three years if your cooling system is currently in good shape. (I just started year three on the SuperTech dexclone I'm running in my Hyundai. I converted over from Hyundai's green silicated snot after a very thorough distilled water flush. I flushed 7 times until the effluent drained water-white, then TASTED it. It tasted like distilled water, though I'm sure chemical analysis would've still uncovered trace amounts of ethylene glycol present. Other than my hair falling out over the past two decades, flat feet, and an inability to sleep through the night without a visit to the bathroom after an evening of carousing, I've suffered no untoward consequences...) I've always suspected (though can't prove) that automakers install radiators with roughly half the capacity of the entire cooling system.
*There's only one licensed blender of the G-05 formula in the U.S. - Ashland's Zerex division. Both Ford and DaimlerChrysler get their antifreeze/coolant from that source. Their only difference are the dye colors used.
