Adding the SCA to Heavy-Duty Coolant
at the Initial Fill
Use the equation that is in Table 16 to determine the
amount of SCA that is required when the cooling
system is initially filled.
Table 16
Equation For Adding The SCA To The Heavy-Duty Coolant 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 17 is an example for using the equation that is
in Table 16 .

Adding The SCA to The Heavy-Duty
Coolant For Maintenance
Heavy-duty antifreeze of all types REQUIRE periodic
additions of an SCA.
Test the antifreeze periodically for the concentration
of SCA. For the interval, refer to the Operation and
Maintenance Manual, "Maintenance Interval
Schedule" (Maintenance Section). Cooling System
Supplemental Coolant Additive (SCA) Test/Add.
Additions of SCA are based on the results of the test.
The size of the cooling system determines the
amount of SCA that is needed.
Use the equation that is in Table 18 to determine the
amount of SCA that is required, if necessary:
Table 18
Equation For Adding The SCA To The Heavy-Duty Coolant
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 19 is an example for using the equation that is
in Table 18 .
