How do you know that the "works with anything" coolants are phosphate free?  Most of them list their ingredients, including something like "antifoaming agents," and "anticorrosion agents."  Those could be anything.  Some also list made up proprietary names of chemicals, which also could be anything, and good luck finding out what they are.  A few of the brands (Zerex is one) state on the container that they are "phosphate free."  Most do not.  Given the tendency of the heads of waterboxers to pit, and the availability of antifreeze that is phosphate free without a doubt, I use that.  Sierra is another phosphate free product, but it is propylene glycol, and I don't know if it is as good a coolant for that reason.  But, GoWesty uses it exclusively, and they sure charge a lot for anything they do.
