This research investigated the properties of antifreeze when it is brought in physical contact with metals. It has been found that when metals are put in contact with antifreeze during the process of engine cooling they cause a change to the antifreeze's physical and chemical properties. The change in coolant properties is connected both with the chemical reactivity of the metal and also with any impurities which the metal may contain.
