ABSTRACT:
A thermostat configured to control engine coolant temperature, a coolant temperature control method and system, includes a thermoelement, arranged to open a main valve upon reaching a predetermined temperature; a heating element arranged, based on an output signal from a controller, to heat said thermoelement, the coolant flowing through the thermostat being exclusively coolant from the radiator. Further, the controller may transmit an output signal to said heating element according to an engine signal received from an engine temperature sensor arranged near the engine block to close one or more coolant flow slots arranged at the thermostat exit until a certain predetermined temperature is sensed. The output signal may be transmitted upon the engine temperature sensor sensing a predetermined temperature.
