Caterpillar ELC Cooling System Maintenance
Caterpillar ELC Extender
Caterpillar ELC Extender is added to the cooling system halfway through the ELC service life. The cooling system should be treated with Extender at 241 500 km (150,000 miles) or one half of the ELC service life. Use the chart below to determine the proper amount of Caterpillar Extender required.Contact your Caterpillar dealer for part numbers and available container sizes. ELC Cooling System Cleaning
CLEAN WATER is the only system cleaning/flushing agent required when ELC is drained from the cooling system.ELC can be recycled. The drained coolant mixture can be "distilled" to remove the ethylene glycol and water for reuse. Contact your Caterpillar dealer for more information.After draining and refilling the cooling system, operate the engine with the radiator filler cap removed until the coolant reaches normal operating temperature and the coolant level stabilizes. Add ELC mixture as necessary to fill the system to the proper level.Changing to Caterpillar ELC
To switch the cooling system from conventional HD coolant/antifreeze to Caterpillar ELC, perform the following steps:1. Drain the cooling system.2. Flush the system with clean water to remove any debris.3. Clean the cooling system with Caterpillar Cooling System Cleaner. Follow the instructions on the label.4. Flush the cooling system with clean water. It is very important to remove all of the cleaning agent.5. Fill the cooling system with clean water. Operate the engine until the cooling system temperature is 49 to 66°C (120 to 150°F).6. Drain the cooling system. Flush the cooling system with clean water.7. Repeat steps 5 and 6. Continue to flush the cooling system with clean water until the draining water is also clean.8. Fill the cooling system with Caterpillar ELC.9. Attach a label to the cooling system to indicate the system has been switched over to Caterpillar ELC.ELC Cooling System Contamination
Mixing ELC with other products reduces the effectiveness of the ELC and shortens the ELC service life. Use only Caterpillar products or commercial products that have passed the Caterpillar EC-1 specification for premixed or concentrate coolants. Use only Caterpillar Extender with Caterpillar ELC. Failure to follow these recommendations can result in shortened cooling system component life.
ELC cooling systems can withstand contamination of up to ten percent of conventional HD coolant/antifreeze. If the contamination exceeds ten percent of the total system capacity, perform either one of the following two procedures:* Drain the cooling system. Flush the system with clean water. Refill the system with ELC.* Maintain the cooling system as if the system is filled with conventional HD coolant/antifreeze.Commercial ELC
If Caterpillar extended life coolant is not used, select a commercial extended life coolant that meets the Caterpillar EC-1 specification. Do not use a product that is labeled as an extended life coolant but does not meet the Caterpillar EC-1 specification. Follow the coolant maintenance guidelines of the commercial ELC supplier. In all cases, use distilled or deionized water or use water that has the properties listed in the Caterpillar Water Quality Limits chart.
