HD Expert ENDURANCE Antifreeze/Coolant is a NAP free, extended life coolant using OAT based corrosion inhibitors for Heavy Duty Diesel engines. It is free from amines, borate, nitrite, phosphate and silicate, meeting some major chemistry restrictions of several OEM’s around the globe. The corrosion inhibitor technology used in this product provides effective corrosion protection to all coolant system metals without the need to use SCA’s. This makes for a genuine premium high performance overall engine coolant which is designed for use in heavy duty diesel engines. It can also be used in gasoline and natural gas powered engines. The product is a concentrate and should be diluted with water.

Applications:
HD Expert ENDURANCE Antifreeze/Coolant is designed to be used in heavy duty applications. The product can also be used in gasoline and natural gas engines, making it a good mixed fleet product. It is recommended for use in heavy duty diesel engines found in applications on-road and off-road, farm, mining and construction equipment, as well as all applications in such areas where mixed gasoline/ natural gas/ diesel engines are present.

Performance Features and Benefits:

• Long life organic additive technology
  For heavy duty diesel applications, when used as directed, the product will provide up to 6 years, 1,000,000 km or 12,000 hours whichever comes first of in-field service life. The product is also suitable in gasoline or natural gas engines, for up to for up to 5 years or 250,000km, whichever comes first.
• Free from amine, borates, nitrites, phosphates and silicates.
  HD Expert ENDURANCE Antifreeze/Coolant does not contain any amines, borates, nitrites, phosphates or silicates and therefore is the recommended choice to meet the major chemistry restrictions of Heavy Duty OEMs around the globe. Being silicate free, HD Expert ENDURANCE Antifreeze/Coolant has no possibility of silicate gelation and other associated fallout issues. When used in long haul or heavy-duty applications, there is no need to add an initial charge of SCA to the fresh coolant.
• Wet sleeve linear cavitation protection
  HD Expert ENDURANCE Antifreeze/Coolant provides excellent wet sleeve liner cavitation protection as determined through fleet testing and the Deere Liner Cavitation Test, ASTM D7583.

Compatibility
This product is fully compatible with other similarly formulated organic additive technology long life engine coolants. The product is also widely compatible with other silicate-free engine coolants. It is also compatible with but does not need coolant SCA’s. It is also compatible with Coolant Extenders that are or have been used with OAT coolant technology.
