AMSOIL Industrial Heavy-Duty Engine Antifreeze/Coolant PG Concentrate features a propylene glycol (PG) formulation that provides maximum cooling system protection in extreme temperatures and operating conditions.

• Surpasses standards for metallic corrosion and erosion to protect common cooling-system metals.
• Polyorganic-acid formulation virtually eliminates scaling problems for excellent cleanliness and performance.
• Protects cylinder liners against cavitation erosion/corrosion pitting for long component life.
• Eliminates the need for supplemental coolant additives (SCAs), extenders and recharging cooling systems, reducing maintenance.
• Compatible with other coolants and all common seal, gasket and hose materials found in cooling systems, helping promote long life and reduce leaks 

OFFERS LOW TOXICITY

• Unlike ethylene-glycol-based coolants, which are inherently toxic, this coolant’s propylene glycol formulation is biodegradable and reduces poisoning risk if ingested by children, pets, livestock or wildlife.

FIGHTS CORROSION & SCALE

• Achieves 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.
• Relies heavily on organic-acid technology, but also strategically uses some inorganic salts to take advantage of their protective properties.
• As a properly formulated HOAT coolant, 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, as well as all plastics and elastomers (hoses, gaskets, etc.).
• Compatible with fully formulated diesel antifreezes and other organic acid technology (OAT) and hybrid organic acid technology (HOAT) formulations.
