Cooling system (Fig. 4.40) is used to maintain normal engine operating temperature. It includes a radiator with thermostat; tubes and channels in the block and the cylinder head, in which the coolant circulates. Driving coolant depends on its temperature and is thermostatically controlled. When starting a cold engine coolant circulates through the first small loop, which is limited to the engine and the heating system. The coolant circulates in the engine. Since the engine is warming up faster. The radiator is connected only when the coolant reaches a certain temperature. As soon as the coolant temperature begins to rise, the thermostat opens and the radiator at the same time closes the small circuit. At operating temperature the coolant circulates through the bottom hose cold fluid from the left of the radiator tank to the water pump which pumps fluid into the engine block, the oil cooler and the cylinder head. Most of the liquid through the then open the upper hose thermostat coolant is fed back to the right, radiator tank, and the other part - the radiator of a vehicle heating system. Springing from the bottom of the radiator cooled liquid after passing loop is heated in hot top gets into the radiator. When passing down the radiator fins hot water cools. When driving the water temperature drops below the prescribed operating temperature, the thermostat again closes the passage through the radiator until the coolant is heated sufficiently.
