Now, I thought that the book of Genesis definatly said that the chicken came before the egg! :>) Now then, gentlemen…to settle this once and for all, the thermostat being in backwards will not overheat the engine. If it would, then we would not need engine heaters in the winter up here in the SD tundra, we’d just put our thermostats in backwards! ?!? :>) However, if you start an engine with a thermostat installed backwards in the cooling system it will prevent the coolant from circulating. Since the coolant can’t get to the radiator to loose the heat that it absorbed from the combustion process taking place, its temperature will continue to rise until the point of equilibrium with the temperature of the explosions occurring inside the cylinders. Since the thermostat produces no heat, it is not the direct cause of overheating, rather the direct cause is the continuing explosions of the gasoline and air mixtures in the cylinders that causes the heat. Of course since installing the thermostat incorrectly (backwards) prevents the coolant from doing its intended function of transferring heat from the combustion chamber to the atmosphere, it is the indirect cause of the temperatures rising to intolerable and unacceptable levels resulting in the condition commonly referred to as overheating. :<( There, that should settle it. The chicken definitely came first…
