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 32 to determine the
amount of SCA that is required, if necessary:
Table 32
Equation For Adding The SCA To The Heavy-Duty Coolant
For Maintenance
V is the total volume of the cooling system.
X is the amount of SCA that is required.
Table 33 is an example for using the equation that is
in Table 32 .

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.
