That is the kind of problem that makes me mad at Gm for not designing a proper radiator cap to check what is in the actual radiator.

I remember that "low coolant" issue now that you mention it. Used to see a lot of those in the shop. Bad sensor, as I recall, though I seem to remember even that didn't always fix it. Pretty sure it's in the reservoir and it was the Dex Cool that would do it in. When I was a service writer I read many articles on these problems but I've managed to forget most of the details I do know that there are so many different coolant variations today that it's difficult to have complete confidence in your choice. If I were doing a 100% flush/fill, I think I'd put something else in there, either yellow or green.
