When referring to the Service Life in table 1, use the interval that occurs first. These coolant change intervals are only achievable with annual S O S Services Level 2 coolant sampling analysis.Refer to the engine Operation and Maintenance Manual for the correct interval for replacement of the cooling system water temperature regulator.Note: For engines that require a maximum of 20% glycol, make sure that the amount of additive in the final mix is appropriate. Example of mixing a 20% glycol solution is given in Table 3.

Total Volume of the Cooling System Add the Following:

10 Gallons 2 Gallons 0.5 Gallons 7.5 Gallons
(1) Volumes can also be in liters as long as all the volume units are consistentExtended life coolants require the one time maintenance addition of an extender at coolant service mid-life. For commercial coolants, do NOT use an extender with a coolant unless the extender has been approved by the coolant manufacturer for use with the coolant. The coolant manufacturer is responsible to ensure compatibility and acceptable performance. Failure to follow these recommendations can result in shortened cooling system component life.Conventional coolants require the maintenance addition of SCA throughout the expected life. For commercial coolants, do NOT use an SCA unless approved by the coolant supplier for use with the coolant. The coolant manufacturer is responsible to ensure compatibility and acceptable performance."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 maximum of 1 year ("ASTM D4985") and 2 years ("ASTM D6210"). The suitability for use requirement is the direct responsibility of the coolant manufacturer and SCA manufacturer. Consult with the coolant and/or SCA manufacturer concerning the suitability of the products for use in a given application.Cat DEAC does not require a treatment with an SCA at the initial fill.A commercial heavy-duty coolant/antifreeze that meets the "ASTM D6210"specification does not require a treatment with an SCA at the initial fill.A commercial heavy-duty coolant/antifreeze that only meets "ASTM D4985", WILL require a treatment with an SCA at the initial fill and has to fulfill all the requirements listed in the “Technical Requirements for Commercial Extended Life Coolants” table.
