Has anyone tested the pH of their coolant? I am a chemist and thought I would check mine to make sure it was not acidic. Well, I was shocked to find the pH around 10, which is basic. I thought maybe it came from using a flushing solutions when I changed from Evans back to ethylene glycol. However, the Prestone was also around pH 10. Since I use distilled/RO water for dilution, there is no buffering capacity and of course the entire solution is at pH 10 also. This seems way to high to me. Anyone have some ideas on this?
Thanks!
