When Caterpillar Extended Life Coolant (ELC) is used, 119-5152 Coolant Extender must be added to the cooling system. See Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations" for all cooling system requirements.

Use a 8T-5296 Coolant Conditioner Test Kit to check the concentration of the coolant.

NOTICE
Mixing ELC with other products will reduce the effectiveness of the coolant. This could result in damage to cooling system components. If Caterpillar products are not available and commercial products must be used, make sure they have passed the Caterpillar EC-1 specification for pre-mixed or concentrate coolants and Caterpillar Extender.
