ENGINE AR-CORE 2053735 - Caterpillar

provides Extended Life Coolant (ELC) for use in the following applications:
Heavy-duty spark ignited gas engines
Heavy-duty diesel engines
Automotive applicationsThe anti-corrosion package for Caterpillar ELC is different from the anti-corrosion package for other coolants. Caterpillar ELC is an ethylene glycol base coolant. However, Caterpillar ELC contains organic corrosion inhibitors and antifoam agents with low amounts of nitrite. Caterpillar ELC has been formulated with the correct amount of these additives in order to provide superior corrosion protection for all metals in engine cooling systems.ELC extends the service life of the coolant to six years. The service life of coolant is also limited by use (service hours). Refer to the specific engine's Operation and Maintenance Manual, "Maintenance Interval Schedule" (Maintenance Section). ELC does not require frequent additions of a Supplemental Coolant Additive (SCA). An Extender is the only additional maintenance that is needed at three years or one half of the ELC service life.A premixed solution of ELC and distilled water is available in a 1:1 concentration. The Premixed ELC provides freeze protection to −36 °C (−33 °F). The Premixed ELC is recommended for the initial fill of the cooling system. The Premixed ELC is also recommended for topping off the cooling system.ELC Concentrate is also available. ELC Concentrate can be used to lower the freezing point to −51 °C (−60 °F).Containers of several sizes are available. Consult your Caterpillar dealer for the part numbers.Note: Caterpillar developed the EC-1 specification. The EC-1 specification is an industry standard. The EC-1 specification defines all of the performance requirements that are needed for an engine coolant to be sold as an extended life coolant for Caterpillar engines. ELC can be used in most of the following types of engines: diesel, gasoline and natural gas. ELC meets the performance requirements of "ASTM D4985" and "ASTM D5345" for heavy-duty low silicate coolant/antifreeze. ELC also meets the performance requirements of "ASTM D3306" and "ASTM D4656" for automotive applications.
