Truegard Global Antifreeze 50/50 - 55 Gallon Drum

Because it is pre-diluted 50/50, this antifreeze is ready to pour directly into the cooling system with no additional water required. Adding extra water would dilute the mixture beyond the intended concentration and reduce both freeze and boil protection.

The pre-mixed 50/50 solution protects against freezing down to -34°F and against boil-over up to 265°F when used with a standard 15-PSI radiator cap system.

A 'Global' antifreeze is designed to meet the cooling system requirements of a wide range of automotive and light truck engines rather than being limited to a single OEM specification. This makes it a versatile choice for mixed fleets or shops servicing multiple vehicle brands.

Borax, nitrates, and amines are additives found in older conventional antifreeze formulas that can be incompatible with certain modern engine alloys and seals, and may contribute to additive depletion over time. A formula free of these compounds is better suited to aluminum-heavy modern engines and is what allows it to carry a 'Global' designation.

The formulation provides corrosion protection for brass, aluminum, steel, cast iron, copper, and solder - covering the full range of metals commonly found in automotive and light truck cooling systems.

Used antifreeze must be disposed of in accordance with local and regional regulations, as it can pick up heavy metals and other contaminants during service. Note that the 100% biodegradable claim applies only to the product in its unused form.
