How can i see the heat of a Stirling engine

Is there any way of seeing how much heat has been building up in my engine? Otherwise what is a good indication of when to stop the engine so it will not explode?

A pretty good indicator is the color of your engine. It starts out blue and cold, and then progresses through green and yellow to red. Once it goes red, it is a pretty good idea to shut it down so it doesn't explode. If you want to be completely safe, turn it off in the yellow stage, although it can be a bit time-consuming to keep watch and letting it cool down more often.
