Heavy-Duty Antifreeze & Coolant

Product code: ANTHD1G-EA

Ethylene Glycol 50/50 Pre-Mix Formulation

AMSOIL Heavy-Duty Antifreeze & Coolant provides superior heat transfer and excellent protection against corrosion, cylinder-liner cavitation, freezing and boilover. It provides maximum protection in extreme temperatures and operating conditions, and provides superior protection for aluminum, steel, cast iron, copper, brass and solder alloys.

Help Prevent Metallic Corrosion and Erosion
Independent tests reveal AMSOIL Antifreeze/Coolants greatly surpass standards for metallic corrosion and erosion, achieving nearly perfect scores in ASTM corrosion and erosion testing on cast aluminum cylinder heads, steel, copper, solder, brass and cast iron and aluminum water pumps.

ASTM D2570 Corrosion Test

ASTM D7583 cavitation test

AMSOIL Antifreeze/Coolants are proprietary formulations that do not contain phosphate, nitrite, silicate, borate or amine found in conventional antifreeze/coolants. These materials are responsible for almost all scaling issues in cooling systems, and they can also precipitate to form scale if the antifreeze/coolant inhibitor system is at the wrong pH or mixed with incompatible products. AMSOIL Antifreeze/Coolants virtually eliminate scaling problems.

Cavitation/Pitting Protection
Heavy-Duty Antifreeze & Coolant effectively protects cylinder liners against cavitation erosion/corrosion pitting, without the problems associated with nitrite technology. Nitrites can cause aluminum corrosion, and they are being banned from coolants used by a growing number of manufacturers in both the heavy-duty and automotive markets. Heavy-Duty Antifreeze & Coolant is a top-performing technology that performs extremely well in ASTM D7583 (John Deere Cavitation Test) testing.

Long-Life Formulations
AMSOIL Antifreeze/Coolants' proprietary formulations provide durable and long-lasting protection of colling system components. Passenger Car/Light Truck Antifreeze & Coolant can be used for 150,000 miles or five years, whichever comes first, in passenger cars and light trucks. Heavy-Duty Antifreeze & Coolant can be used for 1,000,000 miles, 20,000 hours of operation or eight years, whichever comes first, in heavy-duty and off-road applications.

Compatible With Other Fluids
AMSOIL Antifreeze/Coolants are compatible with all ethylene and propylene antifreeze and coolant colors, as well as all plastics and elastomers (hoses, gaskets, etc.) found in cooling systems. However, mixing propylene and ethylene glycol formulations can make it difficult to predict freeze protection. If mixing for top-off is unavoidable, it is recommended to flush the cooling system at the next convenient opportunity.

Use in applications requiring any of the following specifications: ASTM D3306, D6210, D7583, D7820 ‐ TMC RP329B, TMC RP338 ‐ AS/NZS 2108.2004 Type A

Suitable for use with the following: Case New Holland ‐ Cummins 14603 ‐ Cummins 3666132 ‐ DDC 7SE 298, 93K217 ‐ Freightliner 48-22880 ‐ GM Heavy Truck ‐ International Truck and Engine / Navistar CEMS B-1 Type III-A ‐ JIS K2234 ‐ MAN 324 NF ‐ MB DBL 7700 ‐ MTU MTL 5048 ‐ Kenworth RO26-170-97 ‐ Mack 014GS17004, 014GS17009 ‐ PACCAR CS0185 ‐ DAF MAT 74002 ‐ Peterbilt 8502.002 ‐ Scania TB1451 ‐ Volvo Heavy Truck

Protection up to 1,000,000 miles, 20,000 hours or 8 years, whichever comes first.

Heavy-Duty Antifreeze & Coolant is the best option for mixed fleets of both passenger-vehicle and heavy-duty applications that want to use one antifreeze/coolant. Heavy-Duty Antifreeze & Coolant can be used in non-heavy-duty applications, but with a drain interval of 150,000 miles or five years, whichever comes first.

Directions for Use

  • Do not add water.
  • Do not remove radiator cap when engine is hot.
  • Antifreeze/coolant (new or used) is hazardous. Clean up and dispose of properly following local regulations.
  • Check and maintain coolant level at every oil-change interval.
  • Check owner's manual for additional maintenance and top-off guidelines.
