Recommendations for Finished Coolants for use in Cat engines
Coolant Type Recommendations Product Service hours (1)(2) Required Maintenance(3)
Cat ELC, Cat ELI, or commercial coolant that meets Cat EC-1 Preferred Cat ELC 12000 hours or 6 years Add Cat ELC Extender at 6000 service hours or one half of service life
Cat ELI (water based) (4) 12000 hours or 6 years Add Cat ELC Extender at 6000 service hours or one half of service life
Min requirements Cat EC-1 specification and "ASTM D6210" and
Organic Additive Technology (OAT) based on a combination of a monocarboxylic acid and a dicarboxylic acid.Free of phosphate, borate and silicate.
Tolyltriazole: minimum typical concentration of 900 ppm
Nitrite: minimum typical concentration of 500 ppm in new coolants 6000 hours or 6 years Add Extender at 3000 service hours or one half of service life
Cat DEAC, Cat SCA, conventional coolants, and commercial extended life coolants that do not meet EC-1 Acceptable Cat DEAC 3000 hours or 3 years SCA at maintenance intervals
Cat SCA (water based) (4) 3000 hours or 2 years SCA at maintenance intervals
Min requirements for fully formulated Heavy Duty Commercial coolants "ASTM D6210" and
Nitrite (as NO2) concentration: Minimum of 1200 ppm (70 grains/US gal) and maximum of 2400 ppm (140 grains/US gal)
Silicon concentration: minimum of 100 ppm and maximum of 275 ppm 3000 hours or 2 years SCA at maintenance intervals
Min requirements for Commercial coolants requiring SCA precharge. ASTM D4985 and Nitrate (as NO2) concentration: Minimum of 1200 ppm (70 grains/US gal) and maximum of 2400 ppm (140 grains/US gal) Silicon concentration: minimum of 100 ppm and maximum of 275 ppm 3000 hours or 1 year SCA at initial fill and SCA at maintenance intervals
Min requirements for SCA and water (5) Commercial supplemental coolant additive and water having
Nitrite (as NO2) concentration: Minimum of 1200 ppm (70 grains/US gal) and maximum of 2400 ppm (140 grains/US gal)
Silicon concentration: minimum of 100 ppm and maximum of 275 ppm 3000 hours or 1 year Per manufacturer recommendations
(1) New Coolants at 50 volume percent diluted. Coolants that are prediluted at the coolant manufacturer must be diluted with water that meets Reagent 4 "ASTM D1193" requirements.
(2) Maintain the in-service coolant at the given limits.
(3) For appropriate maintenance procedures, refer to the details given in this Chapter. For applications that allow the use of Cat ELI in water, a minimum of 7.5 percent of Cat ELI is recommended. For applications that allow the use of SCA and water, a minimum of 6 percent to a maximum of 8 percent concentration of Cat SCA are recommended.
(4) Water-based coolants are not allowed for use in machines that has NOx reduction aftertreatment devices, in engines that has AATAC and in Marine engines that have SWAC
(5) There are currently no industry standards to define the quality of water-based conventional coolants. To control the quality of SCA and water coolants, the commercial SCA additive package should pass ASTM D6210 when this package is used in a glycol based coolant. Do not use a commercial SCA additive package that only meets the ASTM D3306 or
