id0112f1100700

## Construction

• A wax-type thermostat with a jiggle-pin has been adopted.
• The thermostat body is made of stainless steel with excellent corrosion resistance.

## 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.
