Engine ice

When you say "natural state"... I'm assuming there is a standard or specific mineral/ion content that is preferred for the longest cooling system service life?

 

So just regular tap water or softened water and you're good to go?

 

I did this about 3 years ago there was no mention of not mixing it with distilled water back then. I went about it like I would have with water wetter, mixed according to the bottles instructions for concentration, fast worward and went out to the garage to find the bike sitting in a puddle of water slowly dripping

 

I prefer distilled water, its still ionized so not an aggressive reactant anymore but the dissolved solids are removed by the distillation.

in a pinch ill use bottled drinking water to make up anything lost from evaporation if in at the track or something

 

Thanks for mentioning this. I felt guilty using regular water, if I didn't have distilled to mix with water wetter.

 

I use tap water, If I can drink it I'm sure its good enough for a machine. Anything else the antifreeze additives should be able to take care of.

 

I went through this at the beginning of the 2013 season. I was injured and couldn't race so I started tearing the bike down. I found my radiator was leaking and the cooling system contained a white residue. I had assumed it was from the coolant I was using, but was most likely due to the distilled water.

The radiator was eaten from the inside out. If I isolated it and pressurized it, it would spring a leak at random spots after pinching the pinhole that I had found previously shut.

No more distilled or deionized water for me!

 

Taken from Purple Ice's website (link below):

The water we recommend for any cooling system, especially if little or no antifreeze is to be used is filtered drinking water. Nothing special. Just the bottled drinking water found on the grocery store shelf. Be aware that this is not the same as "spring water" which typically has a higher mineral content. We also recommend against distilled water, as it is more corrosive to soft metals, like aluminum. For low-antifreeze and water-only coolant mixtures, using 1.5 to 2 ounces of Purple Ice per quart of coolant is the ideal dose.

Hmm...motul recommends distilled water to mix with mocool.

 

"Anti-corrosion properties that remain while high temperature and ageing. Low corrosion inhibitors
consumption."

regardless of the terrible English. mo-cool has anti-corrosion stuff in it.
