Antifreeze / Coolant

Heavy Duty Deisel Coolant NMOAT

Extended Life Antifreeze / Coolant with Nitrite and Molybdate

Crystal Clean Heavy Duty NMOAT is prediluted, 50/50 antifreeze/coolant formulated with nitrite and molybdate for extra protection in heavy-duty diesel applications. It contains a well-balanced organic acid technology (OAT) inhibitor system that provides great protection for all cooling system metal components. The product provides year-round protection against freeze-ups, boilovers and engine cooling system corrosion. This antifreeze/coolant also includes ingredients to disperse minor oil leakage, prevent fouling, and control hot surface scaling.

Crystal Clean Heavy Duty NMOAT eliminates the need for chemical filters and supplemental coolant additives (SCA’s). Formulated to be free of phosphate, silicate, amine, and borate. It is compatible with other HD OAT coolants like CAT ELC (EC-1 specification).

  • Meets the performance requirements of RP329, RP338A, RP364, ASTM D6210, ASTM D3306
  • Excellent protection against erosion corrosion by wet sleeve cylinder liner cavitation (liner pitting)
  • Ready-to-use prediluted 50/50
  • Red in color
  • Protects all system metals. In HD applications provides up to 600,000 miles on-highway or up to 12,000 hours off-road service where a well-established monitoring program is in place for testing coolant at least twice a year. Coolant extender is generally needed at half-life (300,000 miles or 6,000 hours) and may be added based on results from coolant sample analysis
