Heavy Duty Concentrate (Green) is a luminous yellow coolant, representing an advanced, fully developed Hybrid technology engine coolant. This Hybrid technology coolant surpasses both conventional and organic acid technology (OAT) engine coolants in terms of durability. This product, low in silicate, phosphate, and amine content, is highly recommended for a wide range of automotive applications, including aluminum-compatible engines, as well as light-duty and heavy-duty diesel engines, such as those found in on-road trucks, off-road vehicles, farming equipment, and marine vessels. Notably, it delivers exceptional high-temperature protection for aluminum components.

A distinctive feature of Heavy Duty Concentrate (Green) is that it does not necessitate an initial dose of supplemental coolant additives (SCAs) during the first fill in heavy-duty diesel applications. This formulation is specially designed to safeguard the wet sleeve liners of heavy-duty diesel engines. The addition of SCAs should be determined by the specific requirements of the vehicle’s original equipment manufacturer (OEM). Moreover, this coolant is fully compatible with coolant filters, heavy-duty diesel SCAs, and coolant extenders, ensuring comprehensive support for your engine’s cooling needs.


The benefits of using Heavy Duty Concentrate (Green):

  • Low in silicate content
  • Phosphate and amine-free
  • Approved by OEMs
  • Compatible with hard water conditions
  • No initial requirement for supplemental coolant additives (SCAs) during the first fill
  • Universally suitable, fully meeting or surpassing industry standards for automotive, light-duty, and heavy-duty diesel applications
  • Compatible with both conventional and OAT coolants (for optimal performance, including extended life and longer intervals between SCA additions, it is recommended to flush and replace old coolant with Heavy Duty Concentrate [Green])
  • Compatible with standard SCAs and coolant extenders
  • Extended lifespan of 6 years, 12,000 hours, or 1,000,000 km, whichever comes first
