Abstract
The present invention relates to an adjustable electronic thermostat valve comprising an actuating means provided with a rod for stroking a chamber of an expendable thermal element, so that temperature at which the thermostat valve opens can be easily adjustable based on driving condition of an automobile by changing the volume of the chamber of the expendable thermal element, whereby a cooling efficiency of the engine is maintained in optimized range. As a result, emission of exhaust gas and consumption of fuel is significantly reduced.
