WARNING: Pressurized system: Hot coolant can cause serious burn. To open cap, stop engine, wait until radiator is cool. Then loosen cap slowly to relieve the pressure.

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 premixed or concentrate coolants and Caterpillar Extender.

Note: This machine is shipped with Extended Life Coolant. Extended Life Coolant is recommended for use.

For information about the addition of Extender to your cooling system, see the Operation and Maintenance Manual, “Cooling System Coolant Extender (ELC) - Add” or consult your Caterpillar dealer.

Flushing the Extended Life Coolant From the Cooling System

Some engines utilize Extended Life Coolant. See the Operation and Maintenance Manual, “Maintenance Interval Schedule” in order to determine the service interval.

If a Extended Life Coolant was previously used, flush the cooling system with clean water. No other cleaning agents are required.
