Going back and looking at some of those jugs, there seems to be a big difference in quality.I emptied the waterbox and system of water before putting the antifreeze in. I didn't blow the lines out though which I guess is where I went wrong. I put in two gallons and ran it for awhile and still had at least a quarter of my waterbox filled with antifreeze. It must have gotten rock solid like the photos above.
