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 10 to determine the
amount of SCA that is required, if necessary:
Table 10
Equation For Adding The SCA To The Heavy-Duty Coolant
For Maintenance
V × 0.023 = X
V is the total volume of the cooling system.
X is the amount of SCA that is required.
Table 11 is an example for using the equation that is
in Table 10 .

Note: Before corrosion inhibitors can be effective the
cooling system must be free from rust, scale and
deposits.

Most commercial cooling system cleaning agents are
corrosive and their use is not recommended by
Perkins.
The cooling system must be thoroughly flushed with
clean water after using cleaning agents.
Cleaning agents for marine or industrial cooling sys-
tem must not be used. These cleaning agents are
very aggressive and can cause damage to cooling
system components.
• Run the engine for approximately 30 minutes and
• Take a sample of the solution from the cooling
• Allow the sample to sit for at least 30 minutes and
• Flush the system with clean water.
• Fill the system with new coolant.
