When Don Steger was out here for our last tech session, he indicated that he's starting to see corrosion problems in cars using the Dex- Cool stuff. Maybe an issue with brass radiator & aluminum engine combination, not really sure (most modern cars are now using aluminum radiators). This may start some kind of holy war on the list, but his recommendation is to stick with the green stuff, and change it no less than every two years.
