Cooling system schematic
(1) Separate circuit water pump
(2) Air compressor
(3) Aftercooler
(4) Separate circuit coolant source Coolant goes in separate circuit water pump (1) through an elbow that connects to the separate circuit coolant source (4). The coolant flow is sent through aftercooler (3).Coolant flows through aftercooler (3) and back to separate circuit coolant source (4).Air compressor (2) is also cooled by the separate circuit cooling system. A small coolant line picks up coolant from the pressure side of the auxiliary water pump. The coolant is then sent through the cylinder head of the air compressor. The coolant then goes back to the suction side of the auxiliary water pump.The radiator provides coolant for the jacket water cooling system and for the separate circuit cooling system. The folded core radiator has individual core assemblies. The core assemblies are designed to increase cooling efficiency and serviceability. Each of these core assemblies can be serviced individually by removing the top tank.There is a low coolant level indicator for the jacket water cooling system and for the separate circuit cooling system. The low coolant level indicators are located on the radiator top tank assembly.
