Caterpillar dealer
Local water utility company
Agricultural agent
Independent laboratoryAdding the Cat SCA to Water at the Initial Fill
The capacity of the cooling system determines the amount ofCat SCA that is required. Use the equation that is in Table 8 to determine the amount ofCat SCA that is required at the initial fill. This equation is for a mixture of onlyCat SCA and water.
Table 8
Equation For Adding TheCat SCA To Water At The Initial Fill
V × 0.08 = X
V is the total volume of the cooling system.
X is the amount ofCat SCA that is required. Table 9 is an example for using the equation that is in Table 8.

(20 US gal) Adding theCat SCA to Water for Maintenance
Test the mixture ofCat SCA and water periodically for the concentration ofCat SCA. For the testing interval, see this Operation and Maintenance Manual, "Maintenance Interval Schedule".Note: Test the concentration of SCA with a 298-5311 Coolant Nitrite Test Kit or perform an S O S Coolant Analysis. The test kit includes the following items: a tool for testing, 30 nitrite test ampoules, instructions, and a case. 294-7420 Test Kitcontains the refill ampoules for the 298-5311 Coolant Nitrite Test Kit. Use the instructions that are included with the test kit toproperly testthe SCA.Note: The 298-5311 Coolant Nitrite Test Kit is not calibrated for testing the levels of nitrite of conventional coolants or extended life coolants.Additions of SCA are based on the results of the test or based on the results of the S O S Coolant Analysis. Test for nitrites more frequently if the results of the analysis need more frequent testing.Use the equation that is in Table 10 to determine the amount ofCat SCA that is required for maintenance.

Equation For Adding theCat SCA To Water For Maintenance
V × 0.023 = X
V is the total volume of the cooling system.
X is the amount of Cat SCA that is required. Table 11 is an example for using the equation that is in Table 10.
