This prediluted, 50/50 antifreeze/coolant is a universal/global, hybrid organic acid technology

(HOAT), extended service, non-phosphate product suitable for automotive/light-duty and heavy-duty diesel applications. Since this is a HOAT extended life antifreeze/coolant, it is compatible with most types of extended life and conventional technology antifreeze/coolants. This coolant is precharged, meaning that it contains a minimum of 1200 ppm nitrites. Its additives effectively control wet sleeve cylinder liner pitting/corrosion in heavy-duty diesel engines.
