The cooling system has six main parts—an engine, a radiator, a water pump, a cooling fan, hoses, and a thermostat, which play an important functions in engine. First, it removes excess heat from the engine; second, it maintains the engine operating temperature where it works most efficiently; and finally, it brings the engine up to the right operating temperature as quickly as possible.

The operating process of engine cooling system works by circulating liquid coolant through Hoses in the engine block and cylinder head. As the coolant flows through these hoses, heat is transferred from the engine components to the coolant. The heated coolant then makes its way through a rubber hose to the radiator in the front of the engine compartment. As it flows through the thin tubes in the radiator, the hot liquid is cooled by the air flow. Once the fluid is cooled, it returns to the engine to absorb more heat. The water pump is to keep the fluid circulating through the system when the engine is running. and thermostat is placed between the engine and the radiator to make sure the coolant stays above a certain preset temperature to ensure the engine runs optimally. If the coolant temperature falls below this temperature, the thermostat blocks the coolant flow to the radiator, forcing the fluid instead through a bypass directly back to the engine. The coolant will continue to circulate like this until the optimal running temperature is achieved, at which point the thermostat will open and allow the coolant back through the radiator to be cooled.
