yeah but it's the nitrate, silicate and all the other stuff free. I saw it on pedros garage while he refilled his, he mixed 50/50 water and this coolant. Does that pressure system thing just help you bleed the cooling system? or does it do anything else?
Also How can I fully get the oil out of my radiators and tubes? a chemical? and also do you guys recommend me taking out the thermostat and cleaning it or just leave it be?
