That's a new one on me. FWIW, I converted to Dexcool in 1997 by completely flushing with distilled water - did 4 fill and drain cycles - then filled with Dexcool. No problems 11 years later. Instead of google, check out www.bobistheoilguy.com and study the antifreeze forum; there are several industry gurus lurking. And, the green stuff was all that was available in 1989 when out cars were introduced; the non-phosphate stuff came out two years later in the Saturn line.

my source is right in your area, New braunfels, do you know corey henderson? i have 2 zr1s one of which i bought that had dexcool in it , 3weeks later poof head gasket went . there are many here that have had this happen to there cars . so you have run a zr1 for 11 years with dexcool in it ? the head gaskets in a zr1 are made from different material than other gaskets . at least thats what i have been told . i just know in my cars i will only run the stuff that is gm spec1825 for our engines . changing head gaskets in these motors is not an easy deal . 400 in tools pulling the motor etc . so to me why take the chance . dexcool is not gm1825 spec and thats good enough for me.
