(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.

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”
