Drain the Cooling System
Stop the engine and allow the engine to cool. Close the water inlet for the separate circuit aftercooler (if equipped). Ensure that the engine will not start when the cooling system is drained.
Loosen the radiator filler cap slowly in order to relieve any pressure. Remove the radiator filler cap. Note: For the location of the coolant drain, see the service literature that is provided by the OEM of the locomotive.

Location of the cooling system drain plugs
(1) Oil cooler
(2) Jacket water pump
(3) Cylinder block Note: If the engine has a jacket water heater, drain the coolant from the heater.
Open the coolant drain. Remove cooling system drain plug (1). Remove cooling system drain plug (2). Remove cooling system drain plug (3). Allow the coolant to drain. Note: If the engine has a separate circuit aftercooler, follow the recommended procedure for draining the aftercooler.
Remove the aftercooler drain plugs. Allow the coolant to drain.
Clean the aftercooler drain plugs. Install the aftercooler drain plugs.
Dispose of used engine coolant properly or recycle. Various methods have been proposed to reclaim used coolant for reuse in engine cooling systems. The full distillation procedure is the only method acceptable by Caterpillar to reclaim the used coolant.
For information regarding the disposal and the recycling of used coolant, consult your Caterpillar dealer or consult Caterpillar Dealer ServiceTools:Outside U.S.A. (309) 675-6277

Clean the Cooling System
After the cooling system has been drained, flush the cooling system with clean water in order to remove any debris.
Close the coolant drain. Clean the drain plugs and install the drain plugs.
Fill the cooling system no faster than 19 L (5 US gal) per minute to avoid air locks.
Open the water inlet for the separate circuit aftercooler (if equipped). Fill the cooling system with clean water. Install the radiator filler cap. Operate the engine until the temperature reaches 49 °C (120 °F) to 66 °C (150 °F).
Stop the engine and allow the engine to cool. Close the water inlet for the separate circuit aftercooler (if equipped). Ensure that the engine will not start when the cooling system is drained. Loosen the radiator filler cap slowly in order to relieve any pressure. Remove the radiator filler cap.
Open the coolant drain. Remove the drain plugs. Allow the coolant to drain. Flush the cooling system with clean water. Close the coolant drain. Install the drain plugs.
Repeat Steps 3, 4, and 5 . Fill the Cooling System
Note: For information about the proper coolant to use, see Special Publication, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations". For the capacity of the cooling system, see this Operation and Maintenance Manual, "Refill Capacities and Recommendations" (Maintenance Section).
Fill the cooling system no faster than 19 L (5 US gal) per minute to avoid air locks.
Fill the cooling system with Extended Life Coolant (ELC). After filling the cooling system, 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. 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 (0.5 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 in 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.
