Extended-Life Heavy-Duty Antifreeze/Coolant 50/50 Pre-Diluted (Red)

XProlube Extended-Life Heavy-Duty Antifreeze/Coolant (Red) 50/50 Pre-Diluted is a fully-formulated, nitrited Organic Acid Technology (NOAT) ethylene-glycol coolant for heavy-duty diesel fleets, ready to use at 50/50. It provides extended service-life freeze/boil-over protection, cylinder-liner cavitation protection, and long-interval corrosion control for HD cooling-system metals — typically supporting extended drain intervals with minimal supplemental coolant additives. Do not mix coolant chemistries.
