•  A wax-type thermostat with a jiggle-pin has been adopted.

•  A flow-control type thermostat has been adopted that controls the amount of engine coolant flowing to the radiator according to the engine coolant temperature.

•  The thermostat body is made of stainless steel with excellent corrosion resistance.

•  When the engine coolant temperature reaches between 83.5—86.5 °C {183—187 °F}, the flow control valve starts opening to let a small amount of engine coolant flow to the radiator. When the engine coolant temperature reaches 86.5—89.5 °C {188—193 °F}, the main valve also starts opening with the flow control valve to increase the engine coolant flow to the radiator, stabilizing the engine coolant temperature. If the engine coolant temperature falls to approx. 80 °C {176 °F}, the valve closes to stop the flow of engine coolant from the engine.
