Beschreibung
Zusammenfassung:	PURPOSE:To insect an operating condition of a thermostat valve in an engine cooling system when testing ignition of the engine., CONSTITUTION:A cooling water circulation passage 5 that circulates the cooling water discharged from a water jacket of an engine 1 is fed back to the water jacket is formed. Consequently, while ignition testing of the engine is performed, an operating condition of a thermostat valve 8 of the water jacket under the condition that the temperature of the circulating cooling water is rising, is observed. After the observation, the circulation passage is switched so that the cooling water is supplied from a by-pass passage 11 of a cooling water supply passage 4 to the water jacket and is discharged to a drainage passage 7 via the cooling water circulation passage 5 and s9olenoid valve 6. The operation of the thermostat valve 8 is detected by means of a thermometer 13 placed in a connection passage 9 connected to the thermostat valve.
