Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
Use only clean water to flush the cooling system when Extended Life Coolant (ELC) is drained and replaced.Drain

(1) Aftercooler drain plug. (2) Oil cooler drain plug. (3) Drain plug for the water temperature regulator.
Open the cooling system drain valve (if equipped). If the cooling system is not equipped with a drain valve, remove the cooling system drain plugs. Remove the drain plug from the bottom of the water cooled exhaust manifold. Remove the drain plug for the water temperature regulator (3), aftercooler drain plug (1) and oil cooler drain plug (2). Allow the coolant to drain.For information regarding the disposal and the recycling of used coolant, consult your Caterpillar dealer or consult Caterpillar Service Technology Group:Outside U.S.A.

Clean the Cooling System
Flush the cooling system with clean water in order to remove any debris.
Close the drain valve (if equipped). Clean the drain plugs. Install the drain plugs. Refer toSpecifications, SENR3130, "Torque Specifications" for more information on the proper torques.
Fill the cooling system no faster than 19 L (5 US gal) per minute to avoid air locks.
Fill the cooling system with clean water. Install the cooling system filler cap. Operate the engine until the temperature reaches 49 °C (120 °F) to 66 °C (150 °F).
Start and run the engine at low idle until the temperature reaches 49 to 66°C (120 to 150°F).
Stop the engine and allow the engine to cool. Loosen the cooling system filler cap slowly in order to relieve any pressure. Remove the cooling system filler cap. Open the drain valve (if equipped) or remove the cooling system drain plugs. Allow the water to drain. Flush the cooling system with clean water. Close the drain valve (if equipped). Clean the drain plugs. Install the drain plugs. Refer to Specifications, SENR3130, "Torque Specifications" for more information on the proper torques. Fill the Cooling System
Engines That Are Equipped with a Coolant Recovery Tank
Fill the cooling system no faster than 19 L (5 US gal) per minute to avoid air locks.
Fill the cooling system to the top with Cat ELC. Refer to this Operation and Maintenance Manual, "Refill Capacities and Recommendations" for more information on coolant specifications. Do not install the filler cap for the recovery tank.
Start and run the engine at low idle. Increase the engine rpm to 1500 rpm. Run the engine at 1500 rpm for one minute in order to purge the air from the cavities of the engine block. 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 cooling system filler cap. Inspect the filler cap gasket. If the filler cap gasket is damaged, discard the old cooling system filler cap and install a new cooling system filler cap. If the filler cap gasket is not damaged, use a 9S-8140 Pressurizing Pump in order to pressure test the cooling system filler cap. The correct pressure for the cooling system filler cap is stamped on the face of the cooling system filler cap. If the cooling system filler cap does not retain the correct pressure, install a new cooling system filler cap.

(1) Filler cap for the recovery tank. (2) "COLD FULL" mark. (3) "LOW ADD" mark.
Pour Cat ELC into the recovery tank until the coolant reaches "COLD FULL" mark (2). Do not fill the tank above "COLD FULL" mark (2).
Clean the filler cap. Install the filler cap. Start the engine. Inspect the cooling system for leaks and for proper operating temperature. Engines That Are Not Equipped with a Coolant Recovery Tank
