6.4.8.2 Task 63. Refill of coolant in the engine cooling system
Refill of LC in the engine cooling system shall be carried out when the lamp indicat-
ing low level of the coolant 16 (Figure 2.7.) lights up on the multifunction display (with the
indicator 9 (Figure 2.9.1) lighting up simultaneously on the multifunction electronic panel).
To refill coolant (LC) in the engine cooling system, perform the following actions:

out up to the moment, when the coolant level in the expansion chamber is below by 50...60
mm the level of the filler neck upper edge;
- cork the expansion chamber 1 with the plug 13.
WARNING: COOLING SYSTEM OPERATES UNDER PRESSURE, WHICH IS
MAINTAINED BY THE VALVE IN THE EXPANSION CHAMBER PLUG. IT IS DANGER-
OUS TO REMOVE THE PLUG WHEN THE ENGINE IS HOT. LET THE ENGINE COOL
