Re: Water in radiator rusty looking
Your results may vary, all I can tell you is what worked for me. Years of rust in the radiator with a SBC with iron heads and aluminum radiator. I tried every combo of additives and lubes from water pump lube to lucas additive and others in between and still had rust, always used distilled water. One year I actually read the directions on the bottle of Lucas coolant additive and it said do not use distilled water. Since then I use Lucas additive with gallon bottles of store bought drinking water. No more rust.
