I have distilled water and RMI 25 for my cooling system. I noticed that the other day (after using the heat all day), my coolant level in the overflow bottle is empty. I have a new heater core, and none of the hoses leak. Is it possible that some of the distilled water evaporated? I was about 40 degrees out when I had the heat on.
I know it has something to do with the heat because the last time I used the heat, the water went down again. I didnt use the heater for about 2 weeks and the level was fine. I used the heat the other day, and now its low!
