I just read the directions on the back of a bottle of Purple Ice and it says not to use distilled water in an aluminum radiator.
What then do you use.....regular bottled water? Why can't you use distilled water in an aluminum radiator???? What harm would it do????
I have used tap water and Water Weter in all of my racebikes (30+) and at one point I had two $12K radiators. All the bikes sit, untouched from Oct 1- at least March 1 every winter and I have never, ever seen anything resembling corrosion.
My Mustang has had tap water and that gold Ford coolant in the alumium radiator and heat exchanger in it since Sept. 06' and the car sits from Nov-Mar every winter and never gets started. It also has zero corrosion.
I can't imagine. The theory behind using distilled water is to eliminate the impurities in tap water that can cause corrosion in your coolant. The coolant acts like electrolyte in the battery and I remember a test where you would use a voltmeter with the + end in the coolant and the - end to ground and check for voltage. More that a certain amount and the coolant needs changing. I don't remember the exact voltage, but it is a measure of electrolytic activity.
I think the warning is corrosion related. Probably because distilled water is partially deionized and it will want to steal ions from the aluminum radiator. With coolant it's a non issue.

I can address this issue from personal experience. I had always used distilled water in my vehicle cooling systems and never had any trouble. In 1985 I started building a show truck and bought a ZZ4 crate engine with aluminum heads and an aluminum radiator and as usual I filled it with distilled water. Less than 13 months and 20,000 miles the engine started showing steam from the exhaust and I began to lose coolant. Upon investigation I found that both the heads and the radiator were perforated as a result of electrolysis cause by the ionized distilled water. If you must use distilled water it is recommended that you use only de-ionized water.
I think the key is not to use deionized water alone in a radiator. If you look at the purple ice disclaimer it states: 'Distilled water and / or demineralized water should not be used if you elect to run a mixture of straight water and Purple Ice in your radiator.'
dang. just when I think I have a good grasp on most of the scientific aspects of owning and maintaining my vehicles for the past 20 years, y'all throw this at me.
de-ionizing?
electron swapping?
stocking distilled water?
gotta be a rocket scientist to maintain a car these days.

I just do what the factory calls for, and with the antifreeze they should not be any problems. Change your antifreeze, and water regularly. Seems pretty simple. Distilled water... I thought was deionized?
Regularly??????? $hit, mine has what the factory put in there from March '05 … damn. I was wondering about the brake and auto tranny fluid too. Change them all:?:
If you go to the shop manual thread in the stickys and look up engine cooling, Ford recommends "deionized" water for their systems. I learn something new everyday on this forum...GA
