Do not change the coolant until you read and understand the material in the Cooling System Specifications section. |

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 specifications 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, "Extended Life Coolant (ELC)" under the topic ELC Cooling System Contamination. This machine was factory filled with Extended Life Coolant. |
If the coolant in the machine is changed to Extended Life Coolant from another type of coolant, see Operation and Maintenance Manual, "Extended Life Coolant (ELC) Cooling System Maintenance".
