I was reading through the official, genuine GM owner's manual for my 2003 Pontiac Vibe it tells you that you can use "drinkable" water, repeatedly:
"A 50/50 mixture of clean, drinkable water and the proper coolant will:"
"What to Use
Use a mixture of one-half clean, drinkable water and one-half coolant that meets GM Specification 1825-M, which won’t damage aluminum parts."
"Use a 50/50 mixture of clean, drinkable water and the proper coolant."
"50/50 mixture of clean, drinkable water (preferable distilled) and good quality
Ethylene Glycol Base Coolant"
The LAST time it casually mentions "preferable distilled".
