Coolant Treatment: See Figure 2-13.
2-16 General Information
1. Engine coolant should be treated with a Diesel Coolant Additive (DCA) to minimize
corrosion of the engine and cooling system components. A 50/50 ethylene glycol
antifreeze solution is recommended for all genset engines. This will provide freeze
protection and increase the boiling point of the engine coolant. A solution can be
increased to 65%. Do not exceed 65% as freeze protection begins to diminish at 65%.
2. It is recommended that the consultant specify Baldor supplied DCA and water filters,
and Baldor antifreeze.
3. When the proper solution concentration of antifreeze is used with radiators (engine
mounted as well as remote mounted), and hot well systems, the system will be
adequately protected from freeze–up.
