    How it works
    When the engine starts, the pulley rotates to drive the impeller of the water pump to rotate, which puts pressure on the cooling system to produce pressure difference so as to drive the coolant to flow out of the outlet channel or water pipe.The center of the impeller leads to pressure reduction because the coolant is pumped away, and the rest of the coolant is sucked into the impeller under the action of pressure difference, so as to realize the flow of coolant in the engine cooling system.The pump bearing is coated with grease to prevent the leakage of coolant into the grease resulting in grease emulsification, and also to prevent the leakage of grease and the high temperature generated by friction.The water seal and gasket are used to prevent the pump from leaking.The water seal seal ring is installed between the impeller and the bearing, and the water seal static seal seat is tightly pressed on the water pump shell, so as to ensure the tightness of the water pump.The pump housing gasket is fixed on the surface of the engine and supports the moving parts such as bearings.The water pump shell is also provided with a drainage hole, located between the water seal and the bearing.Once the coolant leaks through the water seal, it can be discharged from the drain hole to prevent the coolant from entering the bearing cavity and destroying the bearing lubrication and leading to corrosion of the components.
