The thermostat water outlet assembly is the latest in thermostat design. It integrates design elements of both a thermostat and a water outlet. This allows for a simplified design since parts of the water outlet function as the thermostat flange. This also aids in installation because the orientation of the thermostat is fixed in place as the water outlet is bolted to the engine block.
