In North America, diesel fuel that is identified as No. 1-D or No. 2-D in "ASTM D975" generally meet the specifications. These fuels are distilled from crude oil. Diesel fuels from other sources could exhibit detrimental properties that are not defined or controlled by this specification.Refer to Special Publication, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations" for additional information that relates to diesel fuel.Coolant Recommendations
Do not use a commercial coolant/antifreeze that only meets the ASTM "D3306" or equivalent specification. This type of coolant/antifreeze is made for light duty automotive applications.Use only the coolant/antifreeze that is recommended.
The following coolants are the primary types of coolants that are used in Caterpillar Engines:Preferred - Cat ELC (Extended Life Coolant) or a commercial extended life coolant that meets the Caterpillar EC-1 specificationAcceptable - Cat DEAC (Diesel Engine Antifreeze/Coolant) or a commercial heavy-duty coolant/antifreeze that meets "ASTM D4985" or "ASTM D6210" specificationsCaterpillar recommends a 1:1 mixture of water and glycol. This mixture will provide optimum heavy-duty performance as a coolant/antifreeze.Note: Cat DEAC does not require a treatment with a Supplemental Coolant Additive (SCA) at the initial fill. However, a commercial heavy-duty coolant/antifreeze that only meets the "ASTM D4985" 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: These coolants WILL require a treatment with a supplemental coolant additive on a maintenance basis.In stationary engine applications and marine engine applications that do not require protection from boiling or freezing, a mixture of SCA and water is acceptable. Caterpillar recommends a minimum of 6 percent to a maximum of 8 percent SCA concentration in those cooling systems. Distilled water or deionized water is preferred. Water which has the required properties may be used. For the water properties, refer to Special Publication, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations" for additional information that pertains to coolants.Note: Table 2 is a list of the coolants that are recommended and the service life (calendar) of the coolants. The service life of coolant is also limited by use (service hours). Refer to the specific engine Operation and Maintenance Manual, "Maintenance Interval Schedule". To achieve this service life, the coolants must be properly maintained. The maintenance program includes S O S coolant analysis.
