It's not a problem of "will it work", as you can run straight water if you're so inclined. The issue for me is more related to "what buggers my warranty"... I've been told that you have to run only approved coolant, so I'm going to look for the Zerex. They don't carry it at Advance Auto, which is where I usually shop, so will have to cross the street and visit Napa. However, if I run Dex, how on earth would anyone know the difference?? The only test they EVER do of your rad fluid is to test viscocity and temp range. I've never seen them test to insure it's the right product. Watched them working on a Patriot the other day, and the guys says, "looks the right color to me"...lol
