If the crankcase pressure exceeds 15 mbar (150 mm WG),
check the hermetic-tightness of the vehicle vacuum system
(vacuum booster and exhaust gas recirculation systems). In
case of a leak, the vacuum pump forms gauge pressure in the
crankcase, resulting in increased gases flow rate through the oil
separator and discharge of oil with the gases.
Increased pressure of crankcase gases can also be due to
malfunctions of the cylinder-piston group, and clogging of the
crankcase ventilation system components. If this is the case,
clean the components.
ATTenTIon! During operation, do not break hermetic-tightness
of the ventilation system and do not allow the engine to run with the
oil filler opened. This can result in a failure of the turbocharger,
contamination of the engine oil chambers, causing increased oil
entrainment with crankcase gases, and environmental 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 it.
Cooling system
ATTenTIon! The cooling fluid is toxic. Store the fluid in a
tightly closed container. The following rules must be observed during
work with cooling fluid:
- avoid any operations resulting in ingress of the fluid into your
mouth;
- in case of skin contact, do not let the fluid dry on the skin,
and immediately wash it away with warm water and soap;
- wash away any spilled fluid with water and ventilate the room;
- take off any clothing contaminated with the fluid, dry it
outdoors, and then wash it.
Take care when opening the cooling system expansion chamber
plug, to avoid scalding.
For cooling, the following fluid is used: low freezing point
fluid TOSOL-A40M, OZh-40 "Lena", or OZh-40 "TOSOL-TS".
When the ambient air temperature is below -40°C, use the
low freezing point fluid TOSOL-A65M, OZh-65 "Lena", or
OZh-65 "TOSOL-TS".
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 increase to 115°C.
