Mixing Extended Life Coolant (ELC) with other products reduces the effectiveness of the coolant and shortens coolant 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 could result in the damage to cooling systems components. If ELC cooling system contamination occurs refer to Operation and Maintenance Manual, "ELC Cooling System Contamination" . This machine was factory filled with Extended Life Coolant. |
When a Caterpillar Extended Life Coolant (ELC) is used, an Extender must be added to the cooling system. Refer to Operation and Maintenance Manual, "Cooling Recommendations" for all cooling system requirements.
Check the concentration of the coolant. Use a 8T-5296 Coolant Conditioner Test Kit to check the concentration.
