Mark,
Are you using deionized water or distilled water? You may damage your radiator with deionized water as as it is hungry for ions and may attack the solder or other metals in your radiator. I once worked at a Culligan dealership and we sold deionized water to the semiconductor industry. One of our drivers topped up his radiator with our very expensive deionized water and and in a short time his radiator all but fell apart from the water attacking the solder and the copper. Maybe today's radiators are different but just a heads up.
