Cooling System Coolant Extender (ELC) - Add
Caterpillar Extended Life Coolant (ELC) does not require the frequent Supplemental Coolant Additive (SCA) additions which are associated with the present conventional coolants. The Extender only needs to be added once.
Check the cooling system only when the engine is stopped and cool.
- Loosen the cooling system filler cap slowly in order to relieve pressure. Remove the cooling system filler cap.
- It may be necessary to drain enough coolant from the cooling system in order to add the Extender.
- Add Extender according to the requirements for your engine's cooling system capacity. See Special Publication, SEBU6385, "Caterpillar On-highway Diesel Truck Engine Fluids Recommendations" for more information concerning the Caterpillar ELC Extender additions.
- Clean the cooling system filler cap. Inspect the gaskets on the cooling system filler cap. Replace the cooling system filler cap if the gaskets are damaged. Install the cooling system filler cap.
