Level I: Basic Coolant Maintenance Check
Checks for correct chemical balance for proper heat and corrosion control. Tests for: * glycol* SCA concentrations* pH* conductivityS O S Coolant Analysis reports results and makes recommendations, usually within 24 hours.The concentration of SCA should be checked regularly for overconcentration or underconcentration. This should be done with test kits, or S O S Coolant Analysis (Level I) at the Every 250 Service Hours interval.Further coolant analysis is recommended at twice a year or after every 1000 service hours.For example, suppose considerable deposits are found in the water jacket areas on the external cooling system, yet coolant additive concentrations were carefully maintained. Chances are that the coolant water had minerals which deposited on the engine over time.One way to verify the water condition, or to be sure of new water at fill time, is to have a coolant analysis conducted. Full water analysis can sometimes be obtained locally by contacting your local water utility company or an agricultural agent. Private laboratories are also available.Caterpillar recommends S O S Level II Coolant Analysis.Level II: Comprehensive Cooling System Analysis
Completely analyzes coolant and coolant effects on the cooling system. Level II Analysis provides: * full Level I analysis* visual properties inspection* metal corrosion and contaminant identification* identification of built up impurities that point to corrosion and scaling problems BEFORE they lead to costly repairs.Level II Analysis provides a simple, clear report of results, and makes recommendations for the lowest cost corrective options.For more information of coolant analysis and how it can help manage your equipment, see your Caterpillar dealer. Consult your Caterpillar dealer for complete information and assistance in establishing an S O S analysis program for your engine(s).
