AMSOIL Antifreeze & Coolant
Ethylene Glycol 50/50 Pre-Mix Formulations
AMSOIL Passenger Car/Light Truck Antifreeze & Coolant and Heavy- Duty Antifreeze & Coolant 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.
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 aluminium water pumps.
AMSOIL Antifreeze/Coolants are poly-organic acid formulations that do not contain inorganic salts (phosphate, nitrate, nitrite, silicate, borate, amine) found in conventional and hybrid organic acid (HOAT) 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.
AMSOIL Heavy-Duty Antifreeze & Coolant effectively protects cylinder liners against cavitation erosion/corrosion pitting, without the problems associated with nitrite and nitrite/molybdate 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 is a top-performing technology that performs extremely well in ASTM D7583 (John Deere Cavitation Test) testing.
AMSOIL Antifreeze/Coolants do not contain inorganic salts that deplete over time and turn into scale deposits. Their unique blend of organic acids provide durable and long-lasting protection of cooling system components. Passenger Car/Light Truck Antifreeze & Coolant can be used for 150,000 miles or ve years, whichever comes rst, in passenger cars and light trucks. Heavy-Duty Antifreeze & Coolant can be used for 600,000 miles, 12,000 hours of operation or six years, whichever comes rst, 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 dif cult to predict freeze protection. If mixing for top-off is unavoidable, it is recommended to ush the cooling system at the next convenient opportunity.
