Product Description
The water pipe connected to the auxiliary kettle is an indispensable part of the cooling system, so what is the use of the auxiliary kettle connected with the water pipe?
The auxiliary kettle is a vital component of the cooling circuit of water-cooled engine, which plays a role in balancing the pressure of the water tank.
Its working principle is as follows: when the temperature rises, the liquid expands and the pressure rises after the water tank of the automobile engine absorbs the heat of the cylinder, the coolant in the water tank will flow to the auxiliary kettle through the water tank cover of the two-way valve; When the temperature decreases and the pressure of the cooling system is negative, the system sucks the coolant from the auxiliary kettle into the water tank through the water tank cover. So as to balance the pressure of the water tank.
Then why does the auxiliary kettle boil after the car is turned off?
Because when the car stops, the water pump and fan stop working, and the engine water temperature will continue to rise. From the working logic of the auxiliary kettle, we know that the coolant in the water tank will flow to the auxiliary kettle at this time. If there is too much coolant in the auxiliary kettle, when the coolant in the water tank flows in, it will naturally appear that the auxiliary kettle overflows. This is the reason why the auxiliary kettle may overflow after the car is turned off.
The sub-kettle has a corresponding scale indicating the liquid level, which can intuitively know the current water situation. Please pay attention to avoiding the above problems.
