Perkins Generator Cooling System
Mar 12, 2018


The new unit of the Perkins diesel generator unit must be filled with coolant before starting. When filling, the bleed valve of the upper cooling system of the engine should be opened, and the coolant should be slowly added to the engine from the water inlet of the radiator tank until no air bubbles are discharged from the bleed valve. Coolant should be filled under the neck of the heat radiator water inlet, not too full. After filling, the vent valve is closed and the door on the water filter mount is opened so that the DCA4 additive can be mixed into the cooling system. The coolant used in the cooling system is mainly composed of pure water, antifreeze and DCA4 additives. Each liter of coolant contains 50% pure water, 50% antifreeze and 0.5 unit of DCA4 additive. The prepared coolant can be used all year round and can be used continuously for two years.
