Car thermostats for the radiator. You don’t want the coolant flowing when the engine first starts, because it will run like shit. So you have a cylinder filled with wax that expands with heat. That controls a valve to set the flow of coolant. Low tech, works fine, no particular reason to change it.

I thought it was just a spring that expanded with heat and opened/closed with the expansion?
Every one I’ve seen or replaced was just that. No idea what the wax thing is about so I looked it up.

OP’s right!
Is that how the covers over the radiator are operated as well
