Table 18
Equation For Adding The SCA To The Heavy-Duty Coolant At
The Initial Fill
V × 0.07 = 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 .

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 20 to determine the
amount of SCA that is required, if necessary:

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 21 is an example for using the equation that is
in Table 20 .

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 cleaning agents are
very aggressive and can cause damage to cooling
system components.
• Run the engine for approximately 30 minutes and
then leave the engine to cool down.
• Take a sample of the solution from the cooling
system, drain the system.
• Allow the sample to sit for at least 30 minutes and
check for signs of oil and deposits. If oil and
deposits are still present, repeat the procedure.
• Flush the system with clean water.
• Fill the system with new coolant.
