4 – drain stopper of a radiator;

5 – the taking-away (lower) hose of a radiator

In the cooling system of the engine cooling liquid TOSOL-A40 antifreeze is filled in. Cooling system volume (with a heater) –10 liters.

Control of availability of cooling liquid has to be carried out daily before departure. Its level has to be 0 - 10 mm lower than a seam of the top and lower half of a broad tank 2.

Replacement of cooling liquid has to be made through each 60 thousand km of a run (but at least once in 2 years).

Replacement
PERFORMANCE ORDER
1. To put under the engine capacity for liquid discharge:
2. On the engine of fashion 2106 without removing a stopper from a broad tank (for reduction of a pressure of the merged liquid), to turn out the stopper of 1 drain opening located on the left back part of the block of cylinders.
3. On the engine of fashion. 331, 3317 and 3313 to remove the bringing heater hose from a square 1 on the right back part of the block of cylinders of the engine.

4.  To turn out a drain stopper 4 radiators (fig. The bottom view on a cooling system radiator)

5. To turn off a stopper 1 (fig. An arrangement of a broad tank of the cooling system in an engine compartment) a broad tank. At an opportunity to blow system compressed air through a hose 4 steam discharge tubes
6. Upon termination of discharge of liquid to establish drain traffic jams into place
7. To fill in in system through a mouth of a broad tank fresh cooling liquid to the established level in a broad tank. At the same time on the car with the engine of fashion. 2106 to turn off a stopper of 1 opening for production of air. On cars with engines of fashion. 331, 3317 and 3313 gas station of the cooling system is recommended to be made through the taking-away heater hose removed from a square on the bringing branch pipe of the water pump.
8. Upon termination of the procedure to establish a hose into place
9. To wrap a stopper of a broad tank and a stopper of an opening for production of air, to launch the engine. To warm up the engine up to the temperature of 85-90 °C (the valve of the thermostat is open), at which the arrow of the index of temperature of cooling liquid is in a white zone of a scale and to allow it to work 2–3 min. To stop the engine and to allow it to cool down.
10. If after cooling of the engine liquid level falls in a broad tank below established, then it is necessary to restore it (in the absence of dribble traces in the cooling system).


Prevention

After filling of cooling liquid in a broad tank its stopper has to be densely wrapped since liquid at the working and heated-up engine is in the cooling system under pressure. It is necessary to open a stopper of a broad tank for filling of cooling liquid only on the cold engine.
