Over concentration can cause formation of "gel” that can cause restriction, plugging of coolant passages, and overheating. NOTE: If the engine coolant is changed, the coolant filters must also be changed. The cooling system must contain the proper coolant additive units to provide the best chemical protection. Refer to the Engine Specifications. DCA4 Test Kit: Use only DCA4 Coolant Test Kit, Fleet- guard ® Part No. CC-2626 to check the coolant additive concentration in the cooling system.
Coolant Filer/DCA4 Corrosion Resistor Cartridge The correct coolant filter to be used is determined by the total cooling system capacity and other operational factors. Refer to the DCA4 Maintenance Guide in Engine Specifications for the correct selection of the filter. Coolant Filter Replacement Warning: Do not remove the radiator cap from a hot engine. Hot steam will cause serious personal injury. Wait until the coolant temperature is below 50 °C [122 °F] before removing the pressure cap. Remove the coolant system pressure cap and close the shutoff valve before removing the coolant filter. Failure to do so can result in personal injury from heated 51 / 149 pages
