I'm not sure I understand this statement. But just to be safe, a 50/50 premix of Distilled Water and anti-freeze is what is recommended for an aluminum radiator, unless the manufacturer of the automobile it came in or the manufacturer of the radiator recommends something else. Yes, there would have been an advisory of some sort regarding the type of coolant fill whether in an owners manual for the car, the box a radiator is shipped in, or a data sheet inside the box.
To make things clear; tap water, whether from a city water supply or a well, will have varying degrees of chlorides (salts) and other chemicals which are not friendly to aluminum in it. All chlorides are potentially the enemy of aluminum.
