THERMOSTAT CONSTRUCTION/OPERATION [LF]


B3E011201008T10

Construction

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

Operation

• When the engine coolant temperature is below 75.0°C {167°F}, the valve closes and lets the engine coolant circulate inside the engine to improve engine warming performance. When the engine coolant temperature is between 80 °C {176°F} to 84 °C {183°F}, the thermostat begins to open the valve and engine coolant flows to the radiator to stabilize engine coolant temperature.
