Example of Mixing Up a 20% Glycol Coolant (1)    
Total Volume of the Cooling System     Add the Following:    
ELC Concentrate ELI Concentrate     Water    
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. The user and the coolant manufacturer are responsible to ensure the SCA is compatible. Compatibility is based on the recommendations provided by the coolant manufacturer and SCA manufacturer. For example, an extended life coolant that meets the "ASTM D4985" specification may not be compatible with an SCA designed for use with conventional coolants. The coolant manufacturer is responsible to provide sources of compatible SCAs. The coolant manufacturer and SCA manufacturer are responsible to demonstrate a positive influence on reducing cavitation corrosion in an operating diesel engine.Read the label or the instructions that are provided by the manufacturer of the commercial heavy-duty coolant/antifreeze.When adding SCA at initial fill to a coolant/antifreeze that only meets "ASTM D4985", the user and the coolant manufacturer must ensure the SCA is compatible with the antifreeze/coolant. The addition must be 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". Follow the test procedure using the antifreeze/coolant of interest to compare the SCA of interest with the reference SCA.
