Double Turbo VW Water Pump 03C121004J for Car Use

Automotive Engine Parts Double-Turbo Electronic Water Pump 03C121004J For VW

The automobile water pump drives the coolant to heat the engine, ensuring that it circulates in the cooling system, so that the water constantly circulates through the radiator, taking away the heat and ensuring that the engine is not high temperature. The working principle of the engine pump is: the engine drives the pump bearing and impeller to rotate through the pulley, and the cooling liquid in the pump is driven by the impeller to rotate together, and is thrown to the edge of the pump shell under the action of centrifugal force. At the same time, the pump produces a certain pressure, and then flows out of the water channel or water pipe, the center of the impeller due to the coolant is thrown out and the pressure is reduced, the cooling liquid in the water tank is sucked into the impeller through the water pipe under the pressure difference between the inlet of the pump and the center of the impeller, to achieve the reciprocating circulation of the coolant.

The role of car engine water pump

1. The role of the automobile water pump is to pressurize the coolant to ensure its circulation in the cooling system. In layman's terms, it continuously circulates the water through the various parts of the engine block of the heat dissipation weapon to take away the heat to ensure that the engine is not high temperature.
2. In the cylinder block of the car engine, there is a water channel for 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. At the upper water outlet of the engine, there is a water pump, which is driven by the fan belt, so that the hot water in the water channel of the engine block is pumped out and cold water is pumped in.
3. There is 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. At the above, it is turned on, the hot water in the engine is pumped into the water tank, and the cold wind when the car is moving forward blows through the water tank and takes away heat. This is roughly the way it works.
4. The automobile water pump is used to drive the coolant circulation. Only the coolant can be circulated to cool the engine. 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.
