AMSOIL Heavy-Duty Antifreeze & Coolant

AMSOIL 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. AMSOIL Heavy-Duty Antifreeze & Coolant features top-performing technology that performs extremely well in ASTM D7583 (John Deere Cavitation Test) testing.

  • Pre-mixed 50/50 with high-purity water.
  • Fully formulated – DOES NOT require the use of supplemental coolant additives (SCAs) or extenders.
  • Proprietary hybrid organic acid (HOAT) formulation is further enhanced with anti-scalant, anti-fouling and water-pump lubrication additives.
  • Phosphate-, nitrite-, silicate-, borate and amine-free.
  • Boil-over protection up to 265°F with a 15 psi radiator cap.
  • Freeze protection down to -34°F.

AMSOIL Antifreeze & Coolant

Ethylene Glycol 50/50 Pre-Mix Formulations

AMSOIL Passenger Car/Light Truck Antifreeze & Coolant (ANTPC) and Heavy-Duty Antifreeze & Coolant (ANTHD) provide superior heat transfer and excellent protection against corrosion, cylinder-liner cavitation, freezing and boil-over. They provide maximum protection in extreme temperatures and operating conditions, and they provide superior protection for aluminum, steel, cast iron, copper, brass and solder alloys.

AMSOIL Heavy-Duty Coolant (ANTHD)
  • Pre-mixed 50/50 with high-purity water.
  • Fully formulated – DOES NOT require the use of supplemental coolant additives (SCAs) or extenders.
  • Proprietary hybrid organic acid (HOAT) formulation is further enhanced with anti-scalant, anti-fouling and water-pump lubrication additives.
  • Phosphate-, nitrite-, silicate-, borate and amine-free.
  • Boil-over protection up to 265°F with a 15 psi radiator cap.
  • Freeze protection down to -34°F.

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.

Anti-Scale

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

AMSOIL 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. AMSOIL Heavy-Duty Antifreeze & Coolant features 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 cooling system components. AMSOIL 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. AMSOIL 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. Mixing propylene- and ethylene-glycol formulations, however, can make predicting freeze protection difficult. If mixing for top-off is unavoidable, we recommend flushing the cooling system at the next convenient opportunity.

In independent, industry-standard testing, cast iron and copper plates protected by AMSOIL show virtually no signs of corrosion. Based on the ASTM D2570 Corrosion Test.

In independent, industry-standard testing, cylinder liners protected by AMSOIL show virtually no signs of cavitation. Based on the ASTM D7853 Cavitation Test.

SERVICE LIFE

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

Always Amsoil

I had to top off the cooling system in my 2014 Ram 3500 with 209K miles. I switched to Amsoil Heavy Duty when I had the cooling system flushed quite a few miles ago. As with all the lubrication needs on my Ram I trust Amsoil.

Heavy duty coolant

I live in Southeast Texas, I run this product in my diesel pickup and I to say it keeps my truck in excellent working condition, daily driving to towing I’m ready.

Glad I bought it

I was skeptic about this product being different enough to notice. After flushing system and putting in this antifreeze, the temp on my truck dropped 15 degrees and this was on a 108 outside temp. I was shocked. if you have a bunch of miles on your vehicle, do not hesitate. I wish I would have done this a little earlier.
