Adding the SCA to Heavy-Duty Coolant
at the Initial Fill
Use the equation that is in Table 10 to determine the
amount of SCA that is required when the cooling
system is initially filled.
Table 10
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 13 is an example for using the equation that is
in Table 12 .

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 12 to determine the
amount of SCA that is required, if necessary:
Table 12
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 13 is an example for using the equation that is
in Table 12 .

Cleaning the System of Heavy-Duty
Antifreeze
• 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.
