Before the engine flameout, such as the northern part of the Baotou Benz thermostat thermostat valve closed, the impurities in the water may be the main valve on the outlet plug. When water is added, the air inside the engine water jacket is difficult to discharge, resulting in a “gas chamber” phenomenon, the operator mistakenly believe that the water has been filled. When the engine is working, the thermostat is heated so that the valve is opened, and the air in the air chamber flows into the water tank of the water tank.
The elimination method is: in the process of adding water, if the water filled tank is too small, it is proved that the existence of gas chamber. At this time, the northern part of the Baotou Benz parts can be removed thermostat, remove the valve plug, so that the flow of leakage. In order to prevent the emergence of the above phenomenon, the cooling water should be kept clean, and the north part of Baotou Benz parts thermostat should be cleaned regularly.
