Distilled water is the worse thing that you can introduce into a cooling system. This is from my No Rosion/Hypercool manufacturer:
While it certainly is true that distilled water’s purity prevents electrolysis and scale/deposit formation, it unfortunately comes with a potentially very damaging side effect. During the distillation process, water is vaporized into it’s gaseous phase, so all impurities are left behind. These impurities include a number of minerals, including calcium and magnesium – the two components of “hardness.” The water is then condensed back into it’s liquid phase, so the resulting liquid is pure water – in fact, some of the purest water on earth. The problem is that when water is distilled, or “stripped” of impurities, the resulting solution is composed of chemically imbalanced “ions.” This leaves distilled water “electrochemically hungry,” so it will actually strip electrons from the metals in a cooling system as it attempts to chemically re-balance itself. As it chemically removes electrons from the cooling system metals, it does damage that will eventually lead to leaks and system failure."
Even when using additives like antifreeze the distilled water will strip what it needs from the additives shortening it's life.
