Abstract: A thermostat is diagnosed as open failure when a specified time variation in radiator inflow water temperature from a temperature sensor mounted in a first flow path running through a radiator at a time of starting an electric water pump at a cold start of an engine is equal to or greater than a predetermined variation. In the case of open failure of the thermostat, starting the electric water pump causes cooling water from a cooling water flow path of the engine to be flowed to the first flow path, as well as to a second flow path. The radiator inflow water temperature detected by the temperature sensor mounted in the first flow path is raised by the cooling water from the cooling water flow path of the warmed engine.

Abstract: A thermostat device includes a housing having an inlet port and an outlet port. A valve seat is disposed in the housing and has an aperture therein. A first valve opens and closes the aperture under the control of a temperature sensitive device. The temperature sensitive device senses a temperature of fluid supplied to the inlet port, and controls the operation of the first valve based on the sensed temperature. The thermostat also includes a fail safe structure which allows the fluid supplied to the inlet port to flow through a portion of the aperture when the temperature sensitive device malfunctions.
