This Service Bulletin provides guidance on the use of Conventional Fully-Formulated Coolant with SCA, specifically addressing the color change associated with this type of coolant. The bulletin covers a wide range of Freightliner truck models, including the FLA COE, FLB COE, FLD Conventional, Business Class, FLC 112 Conventional, Century Class Conventional, Argosy COE, Cargo, Columbia, Coronado, Business Class M2, Cascadia, and 108SD/114SD. The bulletin outlines the proper procedures for identifying and interpreting the color change of the coolant, as well as the appropriate actions to take based on the observed color change. This information is crucial for ensuring the optimal performance and longevity of the cooling system in these Freightliner trucks.

The Conventional Fully Formulated Coolant with SCA Color Change sb2068 is a high-performance coolant designed specifically for a wide range of Freightliner trucks, encompassing models like the FLA COE, FLB COE, FLD Conventional, Business Class, FLC 112 Conventional, Century Class Conventional, Argosy COE, Cargo, Columbia, Coronado, Business Class M2, Cascadia, 108SD, and 114SD. This coolant is formulated to provide superior protection against corrosion, cavitation, and freezing, ensuring optimal engine performance and longevity. Its advanced SCA (Supplemental Coolant Additive) technology utilizes a color change indicator, allowing drivers to easily monitor the concentration of the coolant and proactively schedule service when necessary. This coolant is formulated with a blend of high-quality ingredients, including inhibitors, anti-freeze, and water, to provide comprehensive protection for the truck's engine cooling system. The corrosion inhibitors prevent rust and scale buildup, extending the life of critical components like the radiator, water pump, and hoses. The anti-freeze component ensures that the engine remains operational in extreme cold temperatures, while the SCA technology helps maintain the pH balance of the coolant, further preventing corrosion and extending the lifespan of the cooling system. The color change feature provides visual confirmation of the coolant's concentration, helping drivers maintain optimal performance and prevent costly breakdowns. By utilizing this coolant, Freightliner truck owners can ensure their vehicles are protected against the harsh environmental conditions they often encounter, leading to increased uptime and reduced maintenance costs.
