1.2.2.6. Cooling System
As seen from Fig. 10, the diesel is cooled by means of the liquid-type cooling system
with forced circulation of the coolant from the centrifugal pump. The temperature of the coolant
in the system is controlled by means of a distance temperature gauge, the sensor of which is
mounted in the cylinder head. In the D-245 diesel engine and its modifications, the place for
mounting the sensor in the thermostat housing is also provided for. The operation of the diesel
engine is prohibited, if the coolant overheating indicator lights up. The temperature of the
coolant in the cooling system must be maintained within 75-95C.
