Thanks for your quick reply, I have read all of the previous posts and frankly I'm more confused. I was told by a notable corvette restorer in so cal that the old style fluid would cause electrolysis in the alloy radiator and block. Have you ever heard of a tech bulletin from GM on this subject. Thanks again
