The pressure tank cover is fine. How can a simple cover be so effective? The principle is the same as that of increasing the boiling point of water in a pressure cooker. The pressure tank cover itself is a pressure relief valve, and the pressure usually set in a car is 1.05 kg/cm². When the water is pressurized, the boiling point of the water will rise.
When the temperature of the liquid in the cooling system increases, the liquid expands, causing the pressure to increase. The pressure tank cover is the only outlet for releasing pressure, so the setting of the spring on the cover determines the maximum pressure of the cooling system. When the pressure reaches 1.05 kg/cm², the pressure valve will be flushed, allowing the coolant to flow out of the cooling system. The coolant enters the bottom of the overflow box through the overflow pipe. This device keeps the air out of the system. When the radiator cools, a vacuum is formed in the cooling system, which will open another spring-loaded valve, and then re-absorb water from the bottom of the overflow box to fill the drained water.

The water tank cover is divided into upper and lower layers. The middle part is a valve core with a spring on it. The valve core is used to block the water filling port. There is a channel on the valve core to communicate with the water tank. When the pressure of the water tank is high, the water pressure pushes up the valve core and the water flows to In the water storage tank, there is a one-way valve in the valve core part. When the water tank is short of water, the water from the single valve storage tank is opened and injected into the water tank. The large cover outside the water tank cover is tightly closed to prevent air leakage. It can’t be filled automatically.
