Information:
You must read and understand the warnings and instructions contained in the Safety section of this manual before performing any operation or maintenance procedures.Cooling System Coolant Extender (ELC)
Add
When a Caterpillar Extended Life Coolant (ELC) is used, an Extender must be added to the cooling system. See the Cooling Recommendations section of this manual for all cooling system requirements.Use a 8T-5296 Coolant Conditioner Test Kit to check the concentration of the coolant.
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 contamination of the ELC cooling system occurs, refer to Extended Life Coolant (ELC) section of this manual for information on the Contamination of the ELC Cooling System. 1. Open the radiator pressure cap access cover. Refer to the General Hazard Information section for information on Containing Fluid Spillage.2. Slowly loosen the radiator pressure cap in order to relieve system pressure. Remove the pressure cap. Refer to the General Hazard Information section for information on Containing Fluid Spillage.3. It may be necessary to drain enough coolant from the radiator so that Caterpillar Extender can be added to the cooling system. Dispose of drained fluids according to local regulations.4. Add Extender to the cooling system. Refer to the following topics for the proper amount of Caterpillar Extender: * Operation and Maintenance Manual, "Extended Life Coolant (ELC)"* Operation and Maintenance Manual, "Refill Capacities"5. Inspect the gasket of the radiator pressure cap. If the gasket is damaged, replace the pressure cap.6. Install the radiator pressure cap.7. Close the radiator pressure cap access cover.
