How do you know when the fluid starts to boil?
Interesting question. I suppose that you could install a thermometer in the cap. It'd be interesting to see which conditions caused temps to rise and cool.

Lacking a cap, IME, it goes suddenly, with essentially no warning between working and failure of the internal pump parts.
