I'm just replacing the thermostat on a car and thought I'd test it before fitting it (I've had my fair share of DOA therms!) Most of the time I just chuck them in a pan of boiling water and see if they open.

This time the therm I'm fitting says it operates at 105c. I've chucked it in a pan of boiling water and it hasn't opened or even started to open. Is that 105c the temperature at which it starts to open or the temperature at which it should be fully open? If it's the former, how does one test it considering I can't get water hotter than 100c?
