Must the car water pump be replaced if it leaks?

[VanClara]

Car water pump leakage must be replaced, as the leakage is caused by damaged seals. If not replaced, the leakage can lead to engine damage. Automotive engines widely use centrifugal water pumps, whose 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 water seal device, making them a major component of the vehicle. The car water pump is located in the engine block, which has multiple water passages for coolant circulation. It is connected to the radiator at the front of the car via hoses, forming a large water circulation system. At the engine's water outlet, a water pump is installed, driven by the fan belt, to pump hot water out of the engine block's water passages and pump cold water in.
