Note: Specific engine applications may require maintenance practices to be periodically evaluated in order to properly maintain the engine’s cooling system.

Table 17 lists part numbers and quantities of SCA that is available from your Caterpillar dealer.

Cleaning the System of Heavy-Duty Coolant/Antifreeze

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 20 to determine the amount of Caterpillar SCA that is required, if necessary:

Table 20

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 21 is an example for using the equation that is in Table 20.

Caterpillar cooling system cleaners are designed to clean the cooling system of harmful scale and corrosion. Caterpillar cooling system cleaners dissolve mineral scale, corrosion products, light oil contamination and sludge.

Clean the cooling system after used coolant is drained or before the cooling system is filled with new coolant.

Clean the cooling system whenever the coolant is contaminated or whenever the coolant is foaming.

For the recommended service interval, refer to the Operation and Maintenance Manual,

“Maintenance Interval Schedule” for your engine.

Commercial Heavy-Duty Coolant/Antifreeze and SCA

SMCS Code: 1350; 1352; 1395

If Caterpillar DEAC is not used, select a coolant/antifreeze with low silicate content for heavy-duty applications that meets “ASTM D5345” or “ASTM D4985” specifications.

Note: When you are not using Caterpillar DEAC the cooling system must be drained one time during every year. The cooling system must be flushed at this time as well.
