All Cat diesel engines equipped with air-to-air aftercooling (ATAAC) require a minimum of 30 percent glycol in order to help prevent water pump cavitation.
Note: Refer to the engine Operation and Maintenance Manual for exceptions.

( 1 ) Whichever comes first.
( 2 ) Refer to the specific engine Operation and Maintenance Manual, "Maintenance Interval Schedule" for the service interval for the cooling system water temperature regulator.
( 3 ) Cat truck engines with excessive idle time must reduce coolant drain intervals to one-half of the stated kilometers/miles recommendations, or base the coolant service life on the stated hours. Engine hours of operation are reported in the ECM (Electronic Control Module). Two examples in which engines may experience excessive idle time are engines that are normally operated in city pickup and delivery applications, and over the road truck applications in which the engines are kept running in order to provide heat and/or air conditioning while the driver sleeps. Refer to the Operation and Maintenance Manual for the specific engine for additional information.
( 4 ) Cat ELC Extender must be added at 6000 service hours or one half of the service life of the Cat ELC.
( 5 ) An extender must be added at 3000 service hours or one half of the service life of the coolant.Note: These coolant change intervals are only achievable with annual S O S Services Level 2 coolant sampling and analysis.Cat ELC, Cat DEAC, Cat Extender, and Cat SCA are available in several container sizes.
