Pressurized system: Hot coolant can cause serious burn. To open cap, stop engine, wait until radiator is cool. Then loosen cap slowly to relieve the pressure. |

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 specification for pre-mixed or concentrate coolants. Use only Caterpillar Extender with Caterpillar ELC. Failure to follow these recommendations can result in shortened cooling system component life. |
When a Caterpillar Extended Life Coolant (ELC) is used, an Extender must be added to the cooling system.
Reference: Refer to Operation and Maintenance Manual, "Cooling System Specifications" for all cooling system requirements or consult your Caterpillar dealer.
Use a 8T-5296 Coolant Test Kit to check the concentration of the coolant solution.

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. |

The cooling system pressure cap is located on the top of the engine enclosure at the front of the machine.
- Slowly remove the cooling system pressure cap in order to relieve system pressure.
- If necessary, drain enough coolant into a suitable container in order to allow the addition of the Extender to the cooling system. The coolant drain valve is located at the bottom of the radiator.
Reference: Refer to Operation and Maintenance Manual, "Extended Life Coolant (ELC)" for the proper amount of Extender that must be added to the cooling system.

- Maintain the coolant level within 13 mm (0.5 inch) of the bottom of the filler pipe.
- Install the cooling system pressure cap. Close the access door.
