I appreciate your sentiment, it really scared me when I came across Dex-Cool's recent history and the fact that GM is standing firm behind this product doesn't sit well with me. I did contact my long-time independant mechanic, Carolina Imports, Craig races corvettes and he has also heard of the horror stories but he uses Dex-Cool in his vette, but he added that he drains & breaks down his engine a lot more than the average street car so he suggested and, you might want to check this out also, to switch to Peak Global coolant which is designed for aluminum block engines. Anyway he said I should sleep better at nights.............Bob
