[V8] Coolant type?

[too many quattros]

why don't you guys use de-ionized water?  my v8 radiator is 15 years old.
my 4000 is at least 18 years old.  maybe older.  infact the only rig i have
ever put a radiator in is a 1984 suburban.  it failed due to welds breaking.
i have had ZERO probs using de-ionized water.
