Guy says distilled water is bad because it pulls minerals, aluminum and iron oxides from the block. Says to use reverse osmosis water or filtered rain water. Go to time 5:55: https://www.youtube.com/watch?v=2ovO1esqzVo Thoughts?

Once antifreeze is added it becomes a coolant loaded with anti corrosion additives.

Either distilled or RO is fine.

Distilled water pulls minerals out of the engine block? Boy that does it right there. I've heard everything now. LOL

I would be more concerned with tap water from a hose. But tens of thousands of people use regular water. Shops use regular water.

To quote a now permabanned member...that's utter bollocks.

Yes, all of those waters are "mineral hungry", they will chew the concrete lining off concrete lined pipes to elevate their hardness...but inside metal receptables, no, they won't eat them.

Power stations we use deionised water inside the boilers and feed system, purified with ion exchange, polished with ion exchange, and ultimately as the water is recirculated through the boiler and turbine many many times...distilled.

Corrosion rates are low, unless air gets into the system...oxides need oxygen.

If we used tap water or rainwater, we'd have scaling as well as corrosion, and intergranular corrosion.

People used tap water forever, demineralised/deionised/distilled is best practice for coolant longevity.


If it's the truth....it can handle the pressure !!!

RO water is corrosive NO!!!!!! It needs plastic or stainless steel in it's equipment. BIG MISTAKE to use RO water. I run a $80,000 RO system at work. You can use it in batteries, but don't use it in a aluminum or steel block, that's just nuts. In fact we had a problem with RO water attacking our chemistry in printing, we have to "pre treat" the virgin RO water to "attack" an additive BEFORE we use it, since it is so aggressive. Distilled is 110% the best water to use in an engine block.

Amazing how anyone can produce a youtube video and people watch it like its true.
Its complete BS, in fact wont even watch it, why add "views" to the person making it, which is why its there to begin with.

Complete nonsense. The issue is with deionized water. And even deionized water is safe once the first bits of antifreeze are added to it.

That is the 'hungry water" theory, originated by Click&Clack, as a joke I assume
