You can check it's not constantly engaged, but you can't check if it will actually engage.

I was wondering if there was a way to apply heat to see if it engages without fecking it up.

Might try a few things to see what happens.

What about putting the coupling in a bowl of hot water?

Was thinking about a blow torch on the nut.
Or the nut submerged in a bowl of boiling water.

I dont know but if you are worried you could stick it in an oven on a low setting.

Not tried it, but I suspect that even if you blow air at it hot enough to activate the bi metal strip, you wouldn't notice any difference in its characteristics unless it was spinning at a few hundred RPM or so.
