It also helps if you only use Dexcool in systems designed for it. Dexcool
can attack some gasket and seal materials and even certain solders and
alloys. If your non-Dexcool system doesn't contain any such materials, you
probably won't have a problem. If your non-Dexcool system DOES contain
such materials, you are setting yourself up for potentially extensive and
expensive damage. I was a slow learner on this one; I had to watch Dexcool
eat three radiators, two heater cors and three head gaskets on three
separate non-GM cars, AND watch the results of dribbling some Dexcool on a
new head gasket, before it got through my head that Dexcool is not
an appropriate choice for just any ol' system.

You have to ask yourself one question: Do you feel lucky?
