How to maintain the radiator of diesel generator set in winter?

Operating diesel generator set will produce huge heat, the generator set will be warmed up if the heat cannot be dissipated properly, the diesel engine will be damaged or its service life will be reduced once the temperature raised to a certain degree. As now is the end of the year, the generator set is usually in a inoperative status, special attention should be paid to the maintenance and operation of the radiator for the generator set.  

First is to change the coolant inside the radiator(water tank). Adding enough antifreeze liquid is recommended to prevent the radiator and the tank from being frozen to crack; second, if no antifreeze liquid is added to the diesel generator set, drain the water inside the machine and radiator empty; third, change the engine oil and diesel. The engine oil which is of a comparatively low concentration is recommended. The diesel whose condensation point is 5 degree lower than normal temperature should be used(to be decided as per areas);fourth, when start the machine, increase the idle running time properly, high speed operation could be used after confirming that the machine temperature has reached the relative temperature, recommended idle running:8-10minutes.
