Draining the Cooling System
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.
Stop the engine and allow the engine to cool. Ensure that the engine will not start when the cooling system is drained.For information regarding the disposal and the recycling of used coolant, consult your Cat dealer or consult Cat Dealer Service Tools Group:Outside Illinois 1-800-542-TOOL

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.
Follow the procedures listed below to drain the cooling system.
Illustration 1 g06253435
(1) Jacket water air vent
(2) SCAC air vent
Illustration 2 g06253319
(3) SCAC water pump drain
Illustration 3 g06253314
(4) Oil cooler drain
(5) Oil cooler drain
(6) Jacket water pump drain

(7) Gas line heater drain
Loosen the cooling system filler cap slowly to relieve any pressure. Remove the cooling system filler cap.
Remove Jacket Water vent (1) and SCAC vent (2).
Remove SCAC drain plug (3).
Remove oil cooler drain plugs (4) ( 5).
Remove water pump drain plug (6).
Remove gas line heater drain plug (7).
If equipped with a jacket water heater, ensure that the shut off valves are open. Remove jacket water heater drain plugs.Clean the Cooling System
Use of commercially available cooling system cleaners may cause damage to cooling system components. Use only cooling system cleaners that are approved for Caterpillar engines.
After the cooling system has been drained, flush the cooling system with clean water to remove any debris.
Close the cooling system drain valves. 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.
If the aftercooler circuit has been drained, the vent plug must be opened to allow the aftercooler to fill properly. Failure to do this will cause an air lock resulting in engine damage.
When the separate circuit is filled, be sure to remove the vent plug.
Fill the cooling system with a mixture of clean water and Caterpillar Fast Acting Cooling System Cleaner. Add 0.5 L (1 pt) of cleaner per 15 L (4 US gal) of the cooling system capacity. Install the cooling system filler cap. Install vent plugs (1).
Start the engine. Operate the engine for a minimum of 30 minutes with a coolant temperature of at least 82 °C (180 °F).
Stop the engine and allow the engine to cool. For the jacket water and the separate circuit, loosen the cooling system filler cap slowly to relieve any pressure. Remove the cooling system filler cap. Open the cooling system drain valves and remove the drain plugs. Remove the vent plugs. Allow the cleaning solution to drain.
Improper or incomplete rinsing of the cooling system can result in damage to copper and other metal components.To avoid damage to the cooling system, make sure to completely flush the cooling system with clear water. Continue to flush the system until all signs of the cleaning agent are gone.
Flush the cooling system with clean water until the water that drains is clean. Close the cooling system drain valves. Clean the drain plugs and install the drain plugs.Cleaning a Cooling System that has Heavy Deposits or Plugging
Note: For the following procedure to be effective, there must be an active flow through the cooling system components.
After the cooling system has been drained, flush the cooling system with clean water to remove any debris.
Close the cooling system drain valves. Clean the drain plugs and install the drain plugs. If the drain plugs include an o-ring seal, inspect the o-ring for damage and replace if necessary.
Ensure that the vent plugs are not installed prior to filling the cooling systems.
Fill the cooling system with a mixture of clean water and Cat Fast Acting Cooling System Cleaner. Add 0.5 L (1 pt) of cleaner per 3.8 to 7.6 L (1 to 2 US gal) of the cooling system capacity. Install the cooling syste
