COUPLING 3006078 - Caterpillar

Note: Specific engine applications may require maintenance practices to be periodically evaluated in order to properly maintain the engine's cooling system.Refer to Table 2 for part numbers and for quantities of SCA.

Adding the SCA to Conventional Coolant/Antifreeze at the Initial Fill
Note: Caterpillar DEAC DOES NOT require an addition of SCA when the cooling system is initially filled.Commercial heavy-duty coolant/antifreeze that meets "ASTM D4985" or "ASTM D5345" specifications MAY require an addition of SCA at the initial fill. Read the label or the instructions that are provided by the OEM of the product.Use the equation that is in Table 3 to determine the amount of Caterpillar SCA that is required when the cooling system is initially filled with the following fluids:
"ASTM D4985"
"ASTM D5345"
Table 3
Equation For Adding The SCA To Conventional Coolant/Antifreeze At The Initial Fill
V × 0.045 = X
V is the total volume of the cooling system.
X is the amount of SCA that is required. Table 4 is an example for using the equation that is in Table 3.

(11 US gal) Adding the SCA to Conventional Coolant/Antifreeze For Maintenance
Heavy duty coolant/antifreeze of all types REQUIRE periodic additions of an SCA.Test the coolant/antifreeze periodically for the concentration of SCA. For the interval, see the Operation and Maintenance Manual, "Maintenance Interval Schedule" (Maintenance Section). SCA test kits are available from your Caterpillar dealer. Test the concentration of SCA or submit a coolant sample to your Caterpillar dealer. See this publication, "S O S Coolant Analysis" topic (Maintenance Section).Additions of SCA are based on the results of the test or based on the results of the coolant analysis. The size of the cooling system determines the amount of SCA that is needed.Use the equation that is in Table 5 to determine the amount of Caterpillar SCA that is required, if necessary:
Table 5
Equation For Adding The SCA To Conventional Coolant/Antifreeze For Maintenance
V × 0.014 = X
V is the total volume of the cooling system.
X is the amount of SCA that is required. Table 6 is an example for using the equation that is in Table 5.
