PAD 3P8593 - Caterpillar

Refer to Table 2 for part numbers and for quantities of SCA.
Table 2
Caterpillar Liquid SCA
Part Number Quantity
6V-3542 0.24 L (8 oz)
111-2372 0.36 L (12 oz)
8T-1589 0.47 L (16 oz)
3P-2044 0.94 L (32 oz)
8C-3680 19 L (5 US gal)
5P-2907 208 L (55 US gal) Maintain the SCA in the same way as you would maintain a cooling system that uses heavy-duty coolant/antifreeze. Adjust the maintenance for the amount of SCA additions. See Table 1 for the amount of SCA that is required.Cooling Systems with Larger Capacities
Adding the SCA to Water at the Initial Fill
Use the equation that is in Table 3 to determine the amount of Caterpillar SCA that is required at the initial fill. This equation is for a mixture of only SCA and water.
Table 3
Equation For Adding The SCA To Water 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 4 is an example for using the equation that is in Table 3.

(18 US gal) Adding the SCA to Water for Maintenance
For the recommended service interval, refer to the Operation and Maintenance Manual, "Maintenance Interval Schedule" for your engine.Use the 8T-5296 Coolant Conditioner Test Kit to test the concentration of SCA. Make the following modifications to Steps 3 and 5 of the 8T-5296 Coolant Conditioner Test Kit instructions:STEP 3 - Add tap water to the vial up to the "20 ml" mark.STEP 5 - When the defined procedure is used, a concentration of six to eight percent will yield between 20 drops and 27 drops. If the number of drops is below 20 drops, the concentration of SCA is low. If the number of drops is above 27 drops, the concentration of SCA is high. Make the appropriate adjustments to the concentration of SCA.Test the concentration of SCA or submit a coolant sample to your Caterpillar dealer. See this publication, "S O S Coolant Analysis" topic (Maintenance Section).Additions of SCA are based on the results of the test or based on the results of the coolant analysis. The size of the cooling system determines the amount of SCA that is required.Use the equation that is in Table 3 to determine the amount of Caterpillar SCA that is required for maintenance, if necessary:

V × 0.023 = X
V is the total volume of the cooling system.
X is the amount of SCA that is required. Table 6 is an example for using the equation that is in Table 3.
