3. COOLING SYSTEM
The Cooling system consists of a radiator (1), centrifugal water pump (2), suction fan (3) and thermostat (4).
The coolant is cooled through the radiator core, and the fan set behind the radiator pulls cooling air through the
core to improve cooling.
The water pump (2) sucks the cooled coolant, forces it into the cylinder block and draws out the hot coolant. Then
the cooling is repeated. Furthermore, to control temperature of coolant, a thermostat is provided in the system. When
the thermostat opens, the coolant moves directly to radiator, but when it closes, the coolant moves toward the water
pump (2) through the bypass between thermostat and water pump (2).
