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 80-
110°C. Short-time (maximum of 5 minutes) engine run is allowed
at cooling fluid temperature increase to 120°C.
When the cooling fluid overheat warning lamp turns on, you
must immediately identify and eliminate the cause of overheating.
From time to time, check the cooling fluid level in the
expansion chamber. The fluid level must be 3-4 cm above the
mark "min". Since the cooling fluid has high thermal expansion
coefficient and the cooling fluid level in the expansion chamber
varies significantly, depending on the temperature, check the
level when the system temperature is +15–20°C.
When the cooling fluid in the expansion chamber decreased
within a short period or after a moderate travel (up to 500 km),
check the cooling system hermetic-tightness and after elimination
of leaks, add the same cooling fluid into the radiator or the
expansion chamber.
In exceptional cases, e.g., major leak of cooling fluid, short-time
filling with pure fresh water into the cooling system is allowed.
Sea water may not be used, nor alkali to soften the water, since
it corrodes the engine's aluminum parts. Prior to use, filter the
water using the materials at hand. As soon as possible, drain the
water completely, flush the cooling system, and fill it with the
cooling fluid specified in Appendix 3.
ATTenTIon! The Manufacturer shall not bear responsibility
for the breakdown of parts caused by freezing of water in the cooling
system.
The cooling system shall be flushed as follows:
- fill the system with pure water, start the engine, let it work
until warm, stop the engine and drain the water;
- repeat the above operation.
Due to presence of air in the interior heater, the temperature
booster and connection hoses, the cooling system shall be charged
as per the following procedure:
- close the cooling fluid drain plugs;
- switch the interior heater valve actuating lever into position
"open";
