(1)When the coolant system is first filled, the SCA is not required to be used with Caterpillar DEAC.
(2)Do not exceed the six percent maximum concentration. Check the concentration of SCA with a SCA test kit.
(3)Do not use the maintenance element for the SCA and the liquid for the SCA at the same time.
Note: Specific engine applications may require maintenance practices to be periodically evaluated in order to properly maintain the engine’s cooling system.
Refer to Table 17 for part numbers and for quantities of SCA.

Cooling Systems with Larger Capacities
Adding the SCA to Conventional Coolant/Antifreeze at the Initial Fill
Note: Caterpillar DEAC DOES NOT require an addition of SCA when the cooling system is initially filled.
Commercial heavy duty coolant/antifreeze that meet “ASTM D4985” or “ASTM D5345” specifications MAY require an addition of SCA at the initial fill. Read the label or the instructions that are provided by the OEM of the product.
Use the equation that is in Table 18 to determine the amount of Caterpillar SCA that is required when the cooling system is initially filled with the following fluids:
•“ASTM D4985”
•“ASTM D5345”
