Fill the cooling system with Extended Life Coolant (ELC). For the correct capacity of the cooling system, refer to the Operation and Maintenance Manual, "Refill Capacities". Do not install the radiator filler cap.
Open the water inlet for the separate circuit aftercooler (if equipped). Start the engine. Operate the engine in order to purge the air from the cavities of the engine block. Allow the ELC to warm and allow the coolant level to stabilize. Run the engine at operating temperature with thermostats opened long enough to sufficiently purge air from the cooling system. Stop the engine.
Check the coolant level. Maintain the coolant to the proper level on the sight gauge (if equipped). If a sight gauge is not equipped, maintain the coolant within 13 mm (.5 inch) below the bottom of the filler pipe.
Clean the radiator filler cap. Inspect the gaskets of the radiator cap.If the gaskets of the radiator filler cap are damaged, discard the old radiator filler cap and install a new radiator filler cap.If the gaskets of the radiator filler cap are not damaged, use a 9S-8140 Pressurizing Pump order to pressure test the radiator filler cap. The correct pressure is stamped on the face of the radiator filler cap. If the radiator filler cap does not maintain the correct pressure, install a new radiator filler cap.
Start the engine. Inspect the cooling system for leaks and for proper operating temperature.
