The Cummins ISB 6.7 engine requires HOAT (Hybrid Organic Acid Technology) antifreeze. A commonly recommended option is Zerex G05, which is available in various colors like yellow, orange, or pink, depending on the brand and packaging. Make sure to use a coolant that meets Cummins CES 14603 specifications for optimal performance and protection.
