Thread: Tap vs. distilled.

Tweet

How many out there use distilled water in your radiators instead of tap along with the coolant. Our tap water has such high mineral content I have been thinking about using distilled.

Sure, why not? Evian ?


Don

I don't use distilled, I'v thought about it, but never have, if it makes you feel better, get a big pot or a pressure cooker from a thrift shop, and boil up some tap water to make distilled, let it boil say, 10 min, then it's ready for the car. replace all rubber coolant lines and flush cooling system entirely b4 putting distilled water in, if not the remaining minerals will mix with the distilled water and it will be tap water again.

Matt,

Just boiling water will not distill it.....unless the water vaporizes and then condenses in another container, the water will still contain impurities...... Remember the picture of grandpa's moonshine still? He boiled the brew and then ran it through a copper coil and into another vessel to condense the brew. It's the evaporation and then condensation of the vapor that takes the impurities out. If you boil a pot of water and vapor escapes, you are making the pot of water MORE impure since you are removing the volume of water but not the minerals.

This is why distilling seawater is so inefficient.....tough to do in a large scale.

Distilled water is sooooo cheap, it cant hurt to use it...buy the stuff in one gallon jugs at the grocery....under a buck a gallon instead of buying Pee-air water.

Water is non-conductive....it's the minerals that make tap water conductive. You can do a Google search on the corrosive effect of mineralized water.....or on the dissolved salts.

In the old days in cold places like Minnesota, the farmers ran kerosene in their cooling systems since it was cheap and had a lower freezing point.

Yes ,Yes use the distilled !!!
