- prevention of corrosion to metals
- prevention of deposit formations of minerals
- prevention of cavitation of the cylinder liners
- elimination of foaming of the coolant
Test the SCA concentration or submit a coolant sample to your CLAAS dealer at every oil change. After every 250 service hours, liquid SCA or a SCA maintenance element may be needed. SCA additions are based on the results of coolant analysis. Your CLAAS dealer has test kits that will evaluate the concentration of additives in Caterpillar DEAC.
The following table indicates the amount of Caterpillar SCA that is needed at the initial fill to treat commercial heavy-duty coolant/antifreezes. The table also shows the addition of an SCA for either liquid SCA or for the maintenance elements of a SCA. These additions are for commercial heavy-duty coolant/antifreezes and for Caterpillar DEAC.

| ( 1 ) | Use a Caterpillar SCA when you do not use a Caterpillar Antifreeze. |
| ( 2 ) | Do not exceed the 6 percent maximum concentration. Check with the supplemental coolant additive test kit. |
Note: Due to the individual engine applications, the maintenance practices need to be periodically reviewed in order to maintain the cooling system.
Cleaning the Heavy-Duty Cooling System
Caterpillar Cooling System Cleaners are designed to clean the system of harmful scale and of corrosion. Caterpillar Cleaners dissolve mineral scale, corrosion products, light oil contamination, and sludge. For the recommended service interval, refer to the Operation and Maintenance Manual, "Maintenance Interval Schedule" for your machine.
