I have a dumb thermostat question. When installing a new thermostat do you put the thermostat in first, then the gasket, then the housing or is it gasket first then the thermostat?
The first thing you should do to a new thermo is check it in a pot of boiling water to see if it opens as soon as you drop it in. Then install as directed if it's good.
My $.02, Good Luck!
