The role of the car engine water pump

1.The function of the automobile water pump is to pressurize the coolant to ensure that it circulates in the cooling system.
2.In the cylinder block of the car engine, there is a water channel for multiple cooling water circulation, which is connected with the radiator (commonly known as the water tank) placed in the front of the car through a water pipe to form a large water circulation system. There is a water pump, driven by the fan belt, to pump out the hot water in the water channel of the engine block, and pump the cold water in.
3.There is also a thermostat next to the water pump. When the car is just started (cold car), it is not turned on, so that the cooling water does not pass through the water tank, but only circulates in the engine (commonly known as small circulation), until the temperature of the engine reaches 80 degrees or more. When the car is turned on, it is turned on, the hot water in the engine is pumped into the water tank, and the cold wind blows through the water tank when the car moves forward, taking away the heat, which is roughly how it works.
The automobile water pump is used to drive the coolant circulation, and the engine can be cooled only when the coolant circulates. The function of the water pump is to pressurize the cooling liquid flowing through the radiator and send it into the cylinder water jacket to facilitate the flow of cooling water.
