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.

\nHelp Prevent Metallic Corrosion and Erosion
\nIndependent 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.

\nAnti-Scale
\nAMSOIL 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.
