Cat ELC
Caterpillar provides Cat ELC (Extended Life Coolant) for use in the following applications:
Heavy-duty diesel engines
Automotive applicationsWhen Cat ELC is compared to conventional coolants, the Cat ELC anti-corrosion package is based on a different additive system. Cat ELC has been formulated with the correct amounts of additives. Superior corrosion protection is provided for all metals that are in engine cooling systems.Cat ELC extends the service life of the coolant to 12000 service hours or 6 years. Cat ELC does not require the frequent addition of the Cat ELC Extender additive. An Extender is the only additional maintenance that is needed at 6000 service hours or one half of the Cat ELC service life.Cat ELC is available in a 1:1 premixed cooling solution with distilled water. The premixed Cat ELC provides freeze protection to −37 °C (−34 °F). The premixed Cat ELC is recommended for the initial fill of the cooling system. The premixed Cat ELC is also recommended for topping off the cooling system.Cat ELC Concentrate is also available. Cat ELC Concentrate can be used to lower the freezing point to −52 °C (−62 °F) for arctic conditions.Containers of several sizes are available. Refer to this Special Publication, "Coolant Recommendations" article for available quantities and part numbers.Note: Cat ELC can be used in most diesel and gasoline OEM engines. Cat ELC meets
