The drain valve of automobile water tank is generally located at the lower right or lower left of the water tank, with different models and different positions. Automobile water tank is mainly composed of radiator core, water pipe, cooling blades, upper water tank and lower water tank.
The upper water tank is on the radiator, and the upper water tank is connected with the water tank below the radiator through a water pipe. When hot water flows from top to bottom to the lower water tank, it becomes warm water, and the cooling blades form a conduit. Through the suction of the fan and the relative wind speed when the car is moving forward, a large amount of cold air passes through the air duct to absorb the heat of the cooling water flowing through the water pipe, and then it is emitted to the atmosphere.
Introduction to the boiling phenomenon of automobile water tank: if the water circulation time is too long, the water will slowly lose, resulting in water shortage in the water tank. If the water is not checked in time, it is easy to cause the water tank to "boil".
Cyclic switching of the thermostat with abnormal size will also lead to "boiling" of the water tank. When the temperature is too high, it can be judged by touching the temperature of the upper and lower water pipes. If the temperature difference between the two water pipes is large, it can be judged that the thermostat is not working properly. There is air in the cooling system, which will form air resistance, make the cooling water circulation not smooth, and cause the engine temperature to be too high.
