The cooling system consists of a radiator (1), a centrifugal water pump (2), a cooling fan (3) and a thermostat (4).
The coolant is cooled through the radiator core, and the cooling fan (3) set behind the radiator (1) pulls cooling air through the radiator core to improve cooling.
The water pump receives water from the radiator or from the cylinder head and force it into the cylinder block.
The thermostat opens or closes according to the water temperature. When the water temperature is high, the thermostat opens to allow the water to flow from the cylinder head to the radiator. When the water temperature is low, the thermostat close to flow the water only to the water pump.
