Heavy-Duty Engine Antifreeze/Coolant PG Concentrate

  • Biodegradable formula limits poisoning risk
  • 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

Heavy-Duty Engine Antifreeze/Coolant PG Concentrate



Propylene glycol (PG) formulation offers the ideal combination of biodegradability and cooling-system protection. Low toxicity limits the threat to children and animals, while providing maximum cooling-system protection in extreme temperatures and operating conditions.

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.
