Not a flame: As the speed of water going through the radiator increases, (and assuming fan operation, and no dirt plugged fins) the greater the heat removed. Delta T is change in temperature. The hotter the entire radiator is, the greater the heat removed from it by the air flow, at a given air temp. Thus removing the thermostat lowers the engine temperature more than having a thermostat in the system. It may not seem correct, but it is truth. The purpose of the thermostat is not to control the speed of water, it is to maintain running temperature of the engine. When approaching any temperature above where the gauge is normally pointing, opens the thermostat more until the point at which it is fully open and flow is not restricted, cooling to the max. A bad thermostat can restrict flow and thus promote overheating. Jim

What’s even more amazing is that all the principals of hydraulic theory can be wrapped up in such a small package.
