About a month ago I read a number of antifreeze threads and freaked out! Last year I had installed all new hoses, clamps, new 180 (& drilled out, as explained on ZR-1 FAQ) stat, & flushed the system. I then used distilled water, water wetter and 10% Prestone. So big mistake using Prestone (as I had read), it has taken a month but I will be receiving my GM antifreeze tomorrow via GM Direct. Then I will re-flush the system and make it 10% with the GM green stuff...I don't drive it in freezing weather & it stays in a heated garage.
So I think I have it right, finally...
