Abstract

PURPOSE: To secure an easy decision for the seal-up degree of a water jacket, by cutting off the pressure source after blocking the water jacket into which the cooled water is not filled yet and applying the pressure into the jacket from an external pressure source and measuring the change of pressure within the jacket.
CONSTITUTION: For the engine 1, the cooled water flow-out port 5 connected to the radiator from the water jacket 4, the flow-out port 6 to the car heater and the return port 7 from the car heater to the jacket 4 are blocked by the caps 8, 9 and 10. And at the same time, hose 13 is connected to the cooled water flow-in port 11. Then the negative pressure supplied from the pressure source 20 is transmitted to the whole jacket 4 by the hoses 19 and 13 and the port 11, and the negative pressure within the jacket 4 reaches the fixed level by the pressure control valve 23. In this instant, the switching valve 22 is closed, and the change of pressure within the jacket 4 is measured by the pressure gauge 21 according to the lapse of time. In such way, the seal-up degree can be decided easily for the water jacket 4.
