How to Fix a Leaking Car Water Pump?
1 Answers
Car water pump leakage can be repaired by: disassembling the water pump, inspecting the water seal, removing the pump cover, loosening the end fastening bolts, and taking out the impeller and water seal assembly. If the static ring or dynamic ring surfaces are damaged and leaking, they can be ground to fit tightly using grinding sand on a cast iron flat plate. If the gasket ring or wave ring is damaged, they should be replaced with new parts. The working principle of a car water pump is: the engine drives the water pump bearing and impeller through the pulley, causing the coolant in the pump to rotate with the impeller. Under centrifugal force, the coolant is thrown to the edge of the pump housing, generating a certain pressure before flowing out through the outlet or water pipe. The center of the impeller experiences reduced pressure as the coolant is thrown outward, allowing the coolant from the radiator to be drawn into the impeller through the water pipe due to the pressure difference between the pump inlet and the impeller center, achieving a reciprocating cycle of the coolant.
