I have heard this both ways. One is using tap water causes deposits and
using distilled water causes it to leach the metals like aluminum into
the water which, in turn, cause deposits to buildup. Personally, I
think the key is to do regular changes of the coolant as antifreeze
contains chemicals to prevent scale buildup and corrosion.
