crankcase ventilation system components. In this case, clean
the components.
During operation, do not break tightness of the ventilation
system and do not allow the engine to run with the oil filler opened.
This can result in failure of the turbocharger, contamination of
the engine oil chambers, causes increased oil entrainment with
crankcase gases and environment pollution.
To clean the crankcase ventilation system, remove the valve
cap, the oil separator cap, ventilation hose and the turbocharger
inlet pipe. Flush the removed parts with kerosene and dry out.
The oil baffle shall be flushed without disassembling.

WARNING!
Coolant is poisonous. Keep it in a tightly closed
container. While using it, obey the following rules:
- avoid any operations as a result of which the liquid can enter
into the mouth cavity;
- do not let the fluid dry out on the skin; wash it off with soap
and warm water;
- flush the spilled fluid with water, air the room;
- remove clothing contaminated with the fluid, dry it outside
the room, and wash it.
Take due care when opening the cap of the expansion tank of
the engine cooling system to avoid a scald.
For coolant, use a low temperature freeze fluid TOSOL-
A40M, OG-40 Lena or OG-40 TOSOL-TC.
At the ambient air temperature -40°C use the low freeze point
fluid TOSOL-A40M, OG-40 Lena or OG-40 TOSOL-TC.
The cooling fluid operating temperature shall be within
60°–110°C. Short-time (maximum of 5 minutes) engine run is
allowed at cooling fluid temperature up to 115°C.
In case the cooling fluid overheat warning lamp turns on, you
must immediately identify and eliminate the cause of overheating.
Check the coolant level periodically in expansion tank 1
(Fig. 3.28), especially if an additional heater is installed. The
fluid level should be 3-4 cm above the MIN mark. Since the
cooling fluid has high thermal expansion coefficient and the
cooling fluid level in the expansion tank varies significantly
depending on the temperature, check the level at the system
temperature of +15-20°C.
