You must read and understand the warnings and instructions contained in the Safety section of this manual, before performing any operation or maintenance procedures.Cooling System
Make sure you read and understand the information in the Safety and Cooling System Specifications sections of this manual before you proceed with cooling system maintenance.
Add Extender (Long Life Coolant/Antifreeze Only)
Extender should be added to LLCA after 3,000 service hours or two years, whichever comes first. The cooling system should be treated with .95 L (1 qt) of Extender for every 46 L (12 US gal) of cooling system capacity.For more Extender information, refer to the Cooling System Specifications LLCA Extender topic in this manual.Drain/Clean/Replace Coolant (Conventional Coolant/Antifreeze Only)
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.
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 replace the thermostat and hoses is when your engine's cooling system has been drained.Drain
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. Open the radiator drain valve. Remove the block and oil cooler drain plugs. Remove the drain plug from the bottom of the water pump housing. Allow the coolant to drain.
Dispose of used engine coolant properly or recycle. Various methods have been proposed to reclaim used coolant 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
