The answer is simple, get the coolent tempature dropper that you can buy through summit, they call it 40 below, and go to your local grocer and get about 4- 5 gallons of distilled water ( or however many gallons your radiator holds ). use this combo and your car will effectivley run 40 degrees cooler. Just make shure you flush the radaitor with real coolant every winter or the block will crack when it freezes.
