Engine cooling system

The role of the automobile cooling system is through the coolant as a temperature transfer carrier, part of the heat absorbed by the heated parts of the timely dissemination of heat, to ensure that the engine works in the most suitable temperature state.

Cooling system mainly consists of water pump, radiator, cooling fan, compensation tank, thermostat, engine body and cylinder head in the water jacket and ancillary equipment.


Water pump: the role of the water pump is to pressurize the coolant to ensure its circulation in the cooling system.


Cooling fan: when the temperature of the water tank is too high, the cooling fan is turned on according to the signal of the temperature sensor, and the rotation of the fan helps to dissipate heat from the water tank.


Water Tank: When the engine is working, the coolant flows inside the water tank core and the air passes outside the water tank core, the hot coolant becomes cold in the water tank due to heat dissipation to the air.
