Anyone here tried flushing the radiator and then replacing with a 75/25 distilled water and water wetter/anti-freeze mix? And can I put straight water and water wetter in the intercooler? I've heard you can't do 100% water even in summer since if you use ac it could be bad. Can someone help on this one? I think the water wetter and water mix with a small amount of antifreeze would really help heat issues. and much cheaper then alcohol injection. Which is another topic I suppose.
