I`m going to use this in the truck and the car: http://www.evanscooling.com/water-based-vs-waterless-differentiators/

wow that has some really great properties, it didnt say if yo uhave to change any mechanical parts though , I wonder with the pressure being lower during operation if you need a higher flow water pump because much of the original works rely on the self pumping action of the heat /pressure to move it along???

that might be the good way to go for even me
