GEAR-PUMP DRIVE 5M5822 - Caterpillar

Use only clean water to flush the cooling system when Extended Life Coolant (ELC) is drained and replaced.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.
Pressurized System: Hot coolant can cause serious burns. To open the cooling system filler cap, stop the engine and wait until the cooling system components are cool. Loosen the cooling system pressure cap slowly in order to relieve the pressure.
Loosen the radiator filler cap slowly in order to relieve any pressure. Remove the radiator filler cap.

(1) Coolant drain
Open coolant drain (1) .
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 Cat dealer or consult Caterpillar Dealer Service Tools:Outside Illinois: 1-800-542-TOOLInside Illinois: 1-800-541-TOOLCanada: 1-800-523-TOOLEAME phone: ++41-22-849 40 56EAME fax: ++41-22-849 49 29Clean 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.
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. Allow the coolant to drain. Flush the cooling system with clean water. Close the coolant drain.
Repeat Steps 3, 4, and 5.Fill the Cooling System
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). For the correct capacity of the cooling system, see this 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. 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
