Coolant boiling out?

The same thing happens to water heaters in homes. Granted, the problem will only happen over a long period of time, but it does happen.

Thanks, I knew that from my automotive experience. I used tap water, but I figured it was only going to be in there for a couple days at most and probably wouldn't cause much harm.

Have been driving around in traffic today and it is a bit cooler, however the temp seems to be behaving. I will be keeping on eye on it for sure though until we get through a summers day of traffic.
