2.1.4. Cooling system

Fig. 2.19. Scheme of operation of the cooling system of the engine 2AZ-FE: 1 – the oil cooler with water cooling; 2 – pump of cooling liquid; 3 – throttle branch pipe; 4 – roundabout channel; 5 – thermostat; 6 – drain crane


The cooling system – closed with compulsory circulation. The thermostat with the bypass valve settles down on the case of the bringing cooling system branch pipe for maintenance of the corresponding distribution of temperatures in the cooling system. It prevents sudden jumps of temperature at warming up of the engine. The stream of cooling liquid does a turn on 180 ° in the block of cylinders of the engine to guarantee smooth course of cooling liquid. Besides, in a head of the block of cylinders and the block of cylinders the roundabout channel is located. Heated liquid from the engine arrives to a throttle branch pipe to prevent its frosting. The oil cooler with water cooling was installed between a case and an oil filter on engines 2AZ-FE.
