Keeping it cool! Nice job Pete.

FYI: I read this on the Corvette Forum...During the distillation process, water is vaporized into its gaseous phase, so all its impurities are left behind. These impurities include a number of minerals, including 'calcium" and "magnesium," the two components of water "hardness." The water is then condensed back into its liquid phase, so the resulting liquid is pure water - in fact, some of the purest water on earth. But the problem is that when water is distilled, or stripped," of its minerals and impurities, the resulting solution is composed of chemically imbalanced "ions." This leaves distilled water "ionically hungry," so it will actually strip electrons from the metals in a cooling system as it attempts to chemically re-balance itself. As it chemically removes electrons from the metals of cooling system components distilled water eventually does extreme damage that could lead to cooling system failure.

I use a 50/50 mix in my C7 as I live in Canada and the car is stored in an unheated garage during the winter months.

4 quarts of concentrate coolant out of 11.8 qts capacity only gets you a 34/66 mix. Close enough? Also it looked like your AC was on while running the heater at full.

40% Coolant /60 % distilled water so we have proportion of 3 liter water and 2 liter coolant when we use 5 liter coolant. For stock corvette c7 z06 2017-2018 year we need 6 liter coolant and 9 liter water. In 2019 model as i guess we need more fluid same with manual transmissions and less in 2015-2016 models.
