Operation

•  When the engine coolant temperature reaches 80—84 °C {176—183 °F}, the valve starts opening to allow engine coolant to flow from the radiator stabilizing the engine coolant temperature. When the engine coolant temperature decreases to approx. 77 °C {171 °F}, the valve closes to stop the engine coolant flow from the radiator.
