Excessive Concentrations of SCA
An excessive concentration of SCA can result in the formation of deposits.If the concentration of SCA is greater than the recommended level, drain some of the coolant/antifreeze. Refill the cooling system with the recommended coolant/antifreeze and operate the engine in order to fully dilute the mixture. Test the concentration again. Repeat this process until the concentration is acceptable.Cooling System Maintenance
Cooling system maintenance has a direct effect on engine operation and on the service life of the engine. Maintain the coolant to the standards that are recommended in the engine's Operation and Maintenance Manual. Refer to the Operation and Maintenance Manual, "Maintenance Interval Schedule". Follow these guidelines:
Use the recommended coolant/antifreeze.
Maintain the proper concentration of SCA. Use the correct method of testing.
Maintain the protection against freezing.
Clean the cooling system and refill the system according to the engine's Operation and Maintenance Manual.
Consult your Caterpillar dealer about S O S coolant analysis.Fluid Products for the Cooling System
