Proper maintenance and prolonged genset life The generator should be filled with coolant before starting. When filling, the deflation valve of the upper cooling system of the engine should be turned over, and the coolant should be slowly added to the engine from the water supply port of the radiator tank until there is no air bubble and then discharged from the vent valve. The coolant should be filled below the neck of the radiator tank and should not be overfilled. At the end of the filling, the deflation valve is closed and the door on the water filter unit is turned open so that the DCA4 additive can be mixed into the cooling system. The cooling liquid used in the cooling system should mainly consist of pure water, antifreeze and DCA4 additive. Each liter of coolant contains 50% pure water, 50% antifreeze and 0.5 unit DCA4 additive. The well-equipped coolant can be used all year round and can be used for two years.

Since pure water is purified, it can avoid the formation of scale generators. Antifreeze means industrial ethylene glycol or propylene glycol, which can lower the freezing point of water and improve the boiling point of water. The concentration of antifreeze should be 40%. 68%, too high or too low concentration will affect the antifreeze ability of the coolant. In most climatic conditions, the recommended antifreeze concentration is 50%, and the freezing point of the coolant can reach -33cC. The DCA4 additive forms a protective film on the inside and outside of the water system to avoid cavitation and blockage of deposits in the liner and the body. The Cummins C-series engines are equipped with a water filter. The water filter contains DCA4 additive in addition to the filter media. The concentration of the DCA4 additive is usually required to be 0.32 to 0.79 units per liter of water and can be detected by the DCA4 test kit.
