It is impossible to fill the system completely with the necessary
coolant volume without engine launch due to the existence of
air in the interior heaters and connecting hoses. Fill the system
as follows:
- set the additional heater (if installed) switcher 5 (Fig. 3.7)
in ON position;
- fill the cooling system with a coolant via an expansion tank
inlet 3-4 cm beyond the MIN mark;
- start the engine, add the cooling fluid to the cooler upper
tank when its level decreases;
- stop the engine, let it cool down, raise the cooling fluid
level in the expansion chamber to the standard and close the
expansion chamber plug;
- run 2-3 cycles of the engine warm-up — cool-down and
raise the cooling fluid level again in the expansion chamber to
the standard.
