Cooling System (Extended Life Coolant Only)
Do not perform this maintenance until you read and understand the material in the Safety and Cooling System Specifications sections of this publication.
Add Extender
Caterpillar Extended Life Coolant (ELC) does not require the frequent Supplemental Coolant Additive (SCA) additions associated with the present conventional coolants. Only a "one time" coolant Extender is required.Extender should be added to ELC Every 3000 Hours or Two Years, whichever comes first.Check the cooling system only when the engine is stopped and cool.1. Loosen the radiator filler cap slowly in order to relieve pressure. Remove the radiator filler cap.2. It may be necessary to drain enough coolant from the cooling system in order to allow for the addition of the Extender.3. Add Extender according to the requirements for your engine's cooling system capacity. Refer to the Refill Capacities chart in this manual for the cooling system capacity for your engine. Refer to the Coolant Specifications in this manual for the Caterpillar ELC Extender Additions chart.4. Clean the radiator filler cap. Inspect the radiator filler cap gaskets. If the gaskets are damaged, replace the old radiator filler cap with a new radiator filler cap. Clean the radiator filler cap receptacle. Install the radiator filler cap.Cooling System (Conventional HD Coolant/Antifreeze Only)
Drain/Clean/Replace Coolant
Do not perform this maintenance until you read and understand the material in the Safety and Cooling System Specifications sections of this publication.
Clean/Flush the cooling system before the recommended maintenance interval if: * Coolant is heavily contaminated.* The engine overheats frequently.* Foaming is observed in the radiator.* The oil cooler has failed, allowing oil to contaminate the coolant.* Fuel has entered the cooling system and contaminated the coolant.* Commercial cooling system products other than Caterpillar products are used.
When using commercial antifreeze/coolant products from a manufacturer other than Caterpillar, drain, clean, and refill the cooling system every year or 1,500 service hours, whichever comes first.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.
A good time to inspect the water pump, replace the thermostat, and replace hoses is when your engine's cooling system has been drained.Drain
Filler Cap (1), Drain Valve (2).1. Stop the engine and allow the engine to cool. Loosen the coolant filler cap slowly to relieve any pressure, and remove the cap.2. Remove the cooling system drain plug(s) or open the drain valve. Remove the drain plug from the bottom of the water pump housing (if equipped) and/or radiator. Allow the coolant to drain.
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 disposal and recycling of used coolant:

3. Flush the cooling system with clean water to remove any debris.4. Clean and install all drain plugs and/or close the drain valve(s).
Fill the cooling system no faster than (19 L) (5 US gal) per minute to avoid air locks.
5. Fill the cooling system with a mixture of clean water and Caterpillar Fast Acting Cooling System Cleaner. Add .5 L (1 pt) of Cleaner per 15 L (4 US gal) of cooling system capacity. Install the radiator filler cap.6. Start and run the engine for a minimum of 30 minutes with the coolant temperature at 82°C (180°F). Stop the engine and allow the engine to cool.7. Loosen the filler cap slowly to relieve any pressure, and remove the cap. Remove the cooling system drain plug(s) or open the drain valve(s). Allow the cleaning solution to drain. Flush the cooling system with clean water until the draining water is clear. Clean and install all drain plugs and/or close the drain valve(s).Fill
Refer to the Cooling System Specifications for all information regarding acceptable water, coolant/antifreeze, and supplemental coolant additive requirements. Refer to the Refill Capacities chart in this publication for the capacity of your engine's system.8. Fill the system with the recommended coolant/antifreeze mixture.9. Start and run the engine with the filler cap removed. Allow the coolant to warm, the thermostat to open and the coolant level to stabilize. Check the coolant level. Add coolant mixture if necessary to bring the coolant to within 13 mm (1/2 in) below the bottom of the fill tube or the correct level on the sight glass (if equipped).10. Check the condition of the filler cap gasket. If the gasket is damaged, discard the old filler cap and install a new filler cap. If the gasket is not damaged, use a 9S8140 Service Tool (available from your Caterpillar dealer) to pressure test the filler cap. The correct filler cap pressure is stamped on the face of the filler cap. If the filler cap does not hold the correct pressure, install a new filler cap.11. Start the engine and inspect for coolant leaks and proper operating temperature. Check for coolant leaks at the oil cooler connections. Stop the engine.Cooling Systems with Heavy Deposits or Plugging
For the following procedure to be effective, there must be some active flow through the radiator and the other cooling system components.Follow the same steps as outlined above, with the following modifications to steps 5 and 6: 5. Fill the cooling system with a mixture of clean water and Caterpillar Fast Acting Cooling System Cleaner. Add .5 L (1 pt) of Cleaner per 3.8 to 7.6 L (1 to 2 US gal) of cooling system capacity. Install the radiator filler cap.6. Start and run the engine for a minimum of 90 minutes with the coolant temperature at 82°C (180°F). Stop the engine and allow the engine to cool.Water Pump Seal
Inspect/Replace
Water PumpOver concentration of coolant additive (Conditioner), mineral deposits from hard water or cooling system contamination can accelerate the wear on the water pump coolant seal. The cooling system maintenance interval provides an opportunity to inspect and replace the water pump seal if necessary to reduce coolant leakage.Check the water
