How often does the engine water pump need to be replaced?

[Alina]

Car engine water pumps typically need replacement after driving 60,000 kilometers. Below is expanded information about engine water pumps: 1. Function of engine water pump: It circulates coolant to enable rapid flow through the engine's cooling channels, carrying away heat generated during engine operation and maintaining proper working temperature. 2. Working principle of engine water pump: A thermostat is installed adjacent to the water pump. When the engine is first started (cold engine), the thermostat remains closed, preventing coolant from flowing through the radiator and only circulating within the engine (commonly called small circulation). When the engine temperature reaches above 80 degrees Celsius, the thermostat opens, allowing hot coolant from the engine to be pumped into the radiator where it's cooled by incoming air as the vehicle moves forward, thereby dissipating heat.
