well back in the 1980'S I began the distilled water and block drain because of the radiator have scale build up on the cooling tubes before Dexcool existed . thats when I stopped using dirty drinking water that scale and corrosion ended. I used the prestone green back then as all had this coolant. the 2000 and 1996 comes with dexcool so when these are changed to a non dexcool / so called compatibles antifreeze this does create problems with black goop being grown .. remember GM approved Dexcool is what to use compatible is not dexcool.
so in 1996 I continued with the distilled in my new 96 impala and then in 2000 the silverado no coolant problems distilled water does work.. drinking water has too many metals and corrosive bacterial killers .. the dexcool is replaced every 4 yrs .
