The device of the cooling system is shown in fig. 2.75.
The cooling system is liquid, the closed type, with compulsory circulation of liquid, with a broad tank.
The pump of cooling liquid of centrifugal type is put in action by a gear belt 17 of the drive of the mechanism of gas distribution.
The electric fan has the plastic four-blade krylchatka 13 established on a shaft of the electric motor 14 which inclusion and switching off is carried out by the controller.
The thermostat 26 with a firm thermosensitive filler has the main and additional valves. The beginning of opening of the main valve at a temperature of cooling liquid (85 ±2) °C, the course of the main valve at achievement of temperature of 102 °C not less than 8 mm.
The radiator is tubular and lamellar, aluminum, with plastic tanks 6 and 9, double-thread, with a partition in the left tank. Cooling liquid is filled in through a bulk mouth of a broad tank 2, a stopper 1 which has inlet and final valves. Pressure of the beginning of opening of the final valve not less than 110 kPa (1,1 kgfs/cm2), inlet – 3–13 kPa (0,03–0,13 kgfs/cm2).
