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 14 to determine the
amount of SCA that is required, if necessary:
Table 14
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 15 is an example for using the equation that is
in Table 14 .

Cleaning the System of Heavy-Duty
Antifreeze
Note: Before corrosion inhibitors can be effective the
cooling system must be free from rust, scale and
deposits.
• Drain the cooling system.
• Before filling the cooling system with acceptable
quality water, pre-dissolve the cleaning agent in
the water. Use a non-foaming detergent to clean
oil contamination, consult your Perkins dealer for
suitable product.
NOTICE
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 areveryaggressiveand
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.

and (ACRA) is recognized by Perkins. For detailed
information about this system, see the latest edition
of the "API publication No. 1509". Engine oils that
bear the API symbol are authorized by API.
