A few years back my thermostat stuck in tne open position and the engine would
never reach a good operating temperature (and the heater and defrost were luke
warm). I sprang for the extra cost of a robertshaw thermostat and did the
stove top test when it got here. Based on the thermometer I was using (candy)
it opened right when it was supposed to. I then installed it and immediately
could see the difference; engine heated up and the heater and defrost were
toasty. The last part is important because as some of you may know I don't
live in a really warm climate. I cannot verify it but I think the mileage went
up, too, because the engine was getting up to a better operating temperature.

I've never tried this trick before: putting the thermostat in a pot of water
and observing the temperature at which it opens.
This is a brand-new, unused 180F thermostat from Otter Zone. Here it's closed
at just under 200F:
And here, it's wide open at just OVER 200F:
It sure seems like a 195 thermostat to me, but it's marked 180.
I dunno.
