Re: direction of thermostat
The way a thermostat works is one side has a tiny plunger and a cavity of wax...the wax is formulated to melt at a certain temperature....when the wax melts the plunger is released and the thermostat opens...when the engine is off and cools down the little piston re-sticks into the wax as it gets solid and the whole process starts over...
The wax is always on the hot side of the water...
