Use Only Approved SCAs and Extenders.Conventional coolants require the maintenance addition of SCA throughout their expected life. Do NOT use an SCA with a coolant unless specifically approved by the coolant supplier for use with their coolant. It is the responsibility of the coolant manufacturer to ensure compatibility and acceptable performance.In order to ensure expected performance, EC-1 coolants require the one time maintenance addition of an extender at coolant service mid-life. Do NOT use an extender with a coolant unless the extender has been specifically approved for use by the coolant manufacturer for use with the coolant. It is the responsibility of the coolant manufacturer to ensure compatibility and acceptable performance.Failure to follow these recommendations can result in shortened cooling system component life.
The following two types of coolants may be used in Cat diesel engines:Preferred - Cat ELC (Extended Life Coolant) or a commercial extended life coolant that meets the Caterpillar EC-1 (Engine Coolant -1) specification.Acceptable - Cat DEAC (Diesel Engine Antifreeze/Coolant) or a commercial heavy-duty antifreeze/coolant that meets "ASTM D4985-05" or "ASTM D6210-06" specificationsChemical Requirements for New Coolant (50 volume % diluted)
Preferred Coolants - Cat ELC or EC-1
Organic Additive Technology (OAT) based on a combination of a monocarboxylic acid and a dicarboxylic acid
Phosphate, borate, and silicate free
Minimum typical tolyltriazole level of 900 ppm
Minimum typical nitrite level of 500 ppm
Coolants that are prediluted at the coolant manufacturer must be diluted with water that meets Reagent 4 ("ASTM D1193") requirementsAcceptable Coolants - Cat DEAC, "ASTM D6210-06", or "ASTM D4985-05" (after the addition of the specification required SCA precharge)
A minimum concentration of nitrite (as NO2-) of 1200 ppm
A minimum silicon concentration of 100 ppm
A maximum silicon concentration of 275 ppm
Coolants that are prediluted at the coolant manufacturer must be diluted with water that meets Reagent 4 ("ASTM D1193") requirementsNote: "ASTM D4985" and "ASTM D6210" require coolants that are properly dosed with SCA and that are in a properly maintained cooling system in normal service to be suitable for use for a minimum of one year ("ASTM D4985") and 2 years ("ASTM D6210"). The suitability for use requirement is the direct responsibility of the coolant manufacturer and SCA manufacturer.
Do not use a commercial coolant/antifreeze that only meets the ASTM "D3306" specification. This type of coolant/antifreeze is made for light duty automotive applications.Use only the coolant/antifreeze that is recommended.
Caterpillar recommends a 1:1 mixture of properly inhibited distilled or deionized water and glycol. This mixture will provide optimum heavy-duty performance as a coolant/antifreeze.Note: Cat DEAC does not require a treatment with an SCA at the initial fill. However, a commercial heavy-duty coolant/antifreeze that only meets "ASTM D4985", by specification, WILL require a treatment with an SCA at the initial fill. A commercial heavy-duty coolant/antifreeze that meets the "ASTM D6210" specification WILL NOT require a treatment with an SCA at the initial fill. Read the label or the instructions that are provided by the manufacturer of the commercial heavy-duty coolant/antifreeze.Note: When adding SCA at initial fill to a coolant/antifreeze that only meets the "ASTM D4985", ensure the SCA is compatible with the antifreeze/coolant. For example, a HOAT coolant that meets the "ASTM D4985" specification may not be compatible with an SCA designed for use with conventional coolants. It is the responsibility of the coolant manufacturer to provide sources of compatible SCAs. It is the responsibility of the coolant manufacturer and SCA manufacturer to demonstrate a positive influence on reducing cavitation corrosion in an operating diesel engine.Note: These coolants WILL require a treatment with a supplemental coolant additive on a maintenance basis.Note: When adding SCA at initial fill to a coolant/antifreeze that only meets the "ASTM D4985", it is a collective responsibility of the user, coolant manufacturer, and SCA manufacturer to ensure the SCA is compatible with the antifreeze/coolant based on the recommendations provided by the coolant manufacturer and SCA manufacturer. One of the test methods required to be used to help ensure SCA compatibility with the antifreeze/coolant concentrate is "ASTM D5828-97". 6% SCA in the solution that is 60 parts antifreeze/coolant of interest, 34 parts water, and 6 parts SCA must have no more than 0.1 mL of formed insolubles. 12% SCA in a solution that is 60 parts antifreeze/coolant of interest, 28 parts water, and 12 parts SCA must have no more than 2 mL of formed insolubles. The SCA manufacturer is responsible for ensuring their SCA is compatible with water meeting the "Caterpillar Minimum Acceptable Water Quality Requirements" as found in this Special Publication and as found in "ASTM D6210-06", Table X1.1.
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.
