Product Spec Sheet:

Sinopec Extended Life Coolant/Antifreeze is formulated with organic corrosion inhibitors to provide total cooling system protection for 1,000,000 miles of on-road use (8 years or 20,000 hours of off-highway use). Since the organic corrosion inhibitors do not readily deplete, Sinopec Life Coolant/Antifreeze eliminates the need for Supplemental Coolant Additives (SCAs) as required when using conventional coolants.

Sinopec Extended Life Coolant/Antifreeze is recommended by ExxonMobil for use in:

  • All types of heavy-duty diesel, gasoline and natural gas engines
  • Stationary engine applications regardless of fuel type being used
  • Marine cooling systems where freeze protection is needed
  • Mixed fleets where both light-duty and heavy-duty trucks are present


Features and benefits

  • 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 Technology (OAT) and Nitrited Organic Acid Technology (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
