Features

  • Long Service Life: 1,000,000 miles of on-road use (8 years or 20,000 hours of off-highway use)
  • Designed for use in engines running EGR, SCR and ACERT technologies that can increase cooling system temperatures
  • Eliminates the cost of SCAs, test strips and manpower required to test the coolant and add SCAs
  • Can accept up to 25% mixing with conventional coolant technologies, with no detrimental effect to corrosion protection or reducing the extended life properties
  • Fully compatible with other quality Organic Acid (OAT) and Nitrited Organic Acid (NOAT) heavy-duty extended life coolants
  • Non-abrasive formula can improve water pump seal life
  • Optimal hard water compatibility and reduced hard water scale
  • Provides outstanding long-term elastomer compatibility
