How Often Should a Car Water Pump Be Replaced?

[VonKevin]

It should be replaced when the mileage reaches 60,000 kilometers. Below is relevant information about car water pumps: Introduction: Centrifugal water pumps are widely used in car engines. Their basic structure consists of components such as the pump housing, connecting plate or pulley, pump shaft and bearings or integrated shaft bearings, pump impeller, and sealing device, making them a major part of the vehicle. Working Principle: The engine drives the pump bearings and impeller to rotate via the pulley. The coolant inside the pump is propelled by the impeller, rotating together and being flung toward the edge of the pump housing under centrifugal force, generating a certain pressure before flowing out through the outlet or hose. The center of the impeller experiences reduced pressure as the coolant is flung outward, causing the coolant in the radiator to be drawn into the impeller through the hose due to the pressure difference between the pump inlet and the impeller center, achieving a reciprocating cycle of the coolant.
