Do not change the coolant until you read and understand the material found in the Operation and Maintenance Manual, "Cooling System Specifications" section. Failure to do so could result in damage to the cooling systems components.
Mixing 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 pre-mixed 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 see the topic ELC Cooling System Contamination of this operation and maintenance manual.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide", for tools and supplies suitable to collect and contain fluids in Caterpillar machines.Dispose of all fluids according to local regulations and mandates.
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" .
