AMSOIL Industrial Heavy-Duty Engine Antifreeze/Coolant EG 50/50 Premix is a robust hybrid-organic-acid-technology (HOAT) coolant that helps prevent corrosion while fighting scale and sludge formation. Its ethylene glycol (EG) formulation is premixed 50/50 with high-purity water to keep cooling systems clean and long-lasting for reduced maintenance and maximum efficiency.

• Formulated to exceed original equipment manufacturer (OEM) requirements and maximize cooling-system component life.
• Premixed 50/50 with high-purity water for maximum convenience.
• Boil-over protection up to 265ºF (129ºC) in a 15-psi closed system.
• Freeze protection down to -34ºF (-36ºC).
• Fortified with anti-deposit, anti-fouling and water-pump lubrication additives.
• Compatible with all common seal, gasket and hose materials found in cooling systems, helping promote long life while helping reduce leaks.
• High-quality organic acid formulation to help avoid IGBT/converter losses.

LONG PUMP & COMPONENT LIFE

• Greatly surpasses standards for metallic corrosion, achieving nearly perfect scores in ASTM corrosion and erosion testing on cast aluminum, steel, copper, solder, brass and cast iron as well as aluminum water pumps.
• Protects pumps to provide long life and reduced maintenance.

HELPS PREVENT DEPOSITS

• Relies heavily on organic-acid technology, but also strategically uses some inorganic salts to take advantage of their protective properties.
• Virtually eliminates scaling, additive dropout, deposits and other problems common to conventional coolants.

COMPATIBLE WITH OTHER COOLANTS

• Can be mixed with all ethylene and propylene glycol antifreeze and coolant colors, allowing operators to top-off any system regardless of the current antifreeze/coolant used.
