How Many Years Does a Car Water Pump Generally Last?

[DelMicah]

Under normal usage conditions, the lifespan of a car water pump can reach up to 10 years, and generally, it is normal to use it for more than 8 years. More relevant information is as follows: 1. How a car water pump works: The engine drives the water pump bearing and impeller to rotate through the pulley. The coolant in the water pump is driven by the impeller to rotate together, and under the action of centrifugal force, it is thrown to the edge of the water pump housing, generating a certain pressure, and then flows out from the water outlet or pipe. Due to the coolant being thrown out, the pressure at the center of the impeller decreases, and the coolant in the radiator is sucked into the impeller through the pipe under the pressure difference between the water pump inlet and the center of the impeller, achieving the reciprocating circulation of the coolant. 2. Note: The direct consequence of most water pump failures is coolant leakage, mostly due to the aging of the water pump seal. In addition, an overly tight engine combination belt can also cause premature wear of the water pump. Not replacing the antifreeze for a long time can lead to internal corrosion, eventually causing damage to the water pump.
