Translating this, it means that distilled water is acidic- about the same 
as Coca Cola in terms of metal dissolving power. So 'DI' water doesn't stay 
pure more than a few minutes after entering your likely already-limed-up 
cooling system and beginning its dissolving act. FWIW, I never use DI water for 
anything except the battery. Good luck- J Deryke
