So I've read about the wisdom of using distilled or deionized water when draining and refilling coolant systems - a task I need to do with all my cars except the G8, since the dealer just replaced the water pump. FWIW, here is the response I got from Prestone on this:
Prestone does recommend mixing deionized/demineralized/distilled water with antifreeze to form the coolant mixture used in your cooling sytem. Retained salts and dissolved solids that are common in tap/well/city/ground water tend to form a layer of deposits on the interior of the cooling system, reducing flow and inhibiting heat transfer. Please let me know if you have any further questions or concerns.
