The function of the automobile water pump is to pressurize the coolant to ensure its circulation in the cooling system. In layman’s terms, it allows water to continuously circulate through the radiator and various parts of the engine block to take away heat and ensure that the engine does not become too hot.

In the cylinder block of a car engine, there is a water channel for cooling water circulation, which is connected to the radiator (commonly known as the water tank) placed at the front of the car through a water pipe to form a large water circulation system. At the upper water outlet of the engine, a There is a water pump, driven by the fan belt, to pump hot water out of the water channel in the engine block and pump cold water in.

There is a thermostat next to the water pump. When the car is just started (cold car), it is not opened so that the cooling water does not pass through the water tank and only circulates in the engine (commonly known as small circulation) until the engine temperature reaches above 80 degrees. When the car is turned on, the hot water in the engine is pumped into the water tank. When the car moves forward, the cold air blows through the water tank and takes away the heat. This is roughly how it works.

The car water pump is used to drive the coolant circulation. Only when the coolant circulates can the engine cool down. The function of the water pump is to pressurize the coolant flowing through the radiator and send it into the cylinder water jacket to facilitate the flow of cooling water.
