CAUTION!
In order to avoid overheating of the cooling fluid, it is necessary to see for
the absence of fouling of the water radiator plates.
To this end, when working in dusty
conditions, it is necessary to perform radiator blowdown with compressed air under the
pressure of 5...7 kgf/cm
2
during every shift at both sides -
from the radiator’s front and from
the fan casing side.
In case of a repeated overheating of the engine, it is necessary to thoroughly check
the condition of the radiator core. In particular, see for the absence of fouling between
radiator plates by checking clearances therein with the help of a standard portable
lamp. If needed, blow down or (in case when dirt is not removed with blowdown)
wash the radiator core with water under the pressure of 5...7 kgf/cm

In order to enhance the effectiveness of cleaning of the radiator block cores from dust, chaff,
etc., the possibility of separation of oil radiator block 1 from engine cooling block 2 is provid-
ed for the tractors.
