Subject: Thermostat
I was trying to check the thermostat sitting in the elbow above the cylinder head. I do not understand how it should work, I think something is missing (broken away).
When I heat it in the kitchen, the pin in the middle closes the little hole in the middle of the brass part but all the openings around let always water through, so there is no difference in flow then.
It looks very difficult to remove the brass part, looks like somebody tried it and did not succeed (creating two holes right and left in the brass part, probably by hammering on a screwdriver).
In the other image you see a little brass pin which looks like a snapped off screw, what is it for ?
So my questions: how does it work, how can it be removed, and is there replacement available or what is mising ? (or do I misunderstand the function)
