conventional heavy-duty coolant/antifreeze, check the concentration of supplemental coolant additive (SCA) regularly. The concentration of SCA can be checked with an S O S coolant analysis (Level I). A more detailed coolant analysis is recommended periodically.For example, considerable deposits are found in the water jacket areas on the external cooling system, but the concentrations of coolant additives were carefully maintained. The coolant water probably contained minerals which were deposited on the engine over time.A coolant analysis can be conducted in order to verify the condition of the water that is being used in the cooling system. A full water analysis may be obtained from the following sources:
Caterpillar dealer
Local water utility company

Independent laboratoryCaterpillar recommends an S O S coolant analysis (Level II). This is a comprehensive chemical evaluation of the coolant. This analysis is also a check of the overall condition of the inside of the cooling system. The following services are provided:
Full Level I analysis
Identification of the source of metal corrosion and of contaminants
Identification of buildup of the impurities that cause corrosion
Identification of buildup of the impurities that cause scaling
Determination of possible electrolysis within the engines' cooling systemA report of the results of the analysis is provided. Maintenance recommendations are based on the results.For more information about S O S coolant analysis, consult your Caterpillar dealer.
