HEAVY-DUTY ANTIFREEZE & COOLANT

AMSOIL Heavy-Duty Antifreeze & Coolant provides superior heat transfer and exceptional protection against corrosion, cylinder-liner cavitation, freezing, and boil-over. Designed for extreme temperatures and operating conditions, it is fully compatible with all plastics, elastomers (hoses, gaskets), and cooling-system metals including aluminum, steel, cast iron, copper, brass, and solder alloys. It is also compatible with all other antifreeze and coolant colors.
