Because this is a full-strength concentrate, it must be mixed with water before use and should never be added to the cooling system undiluted. The product's stated protection range of -34°F to 265°F (with a 15-PSI radiator cap system) reflects a diluted mixture - consult the technical data sheet for the recommended water-to-concentrate ratio that achieves your specific freeze and boil-over protection targets.
The 'Global' designation indicates this antifreeze is engineered to work across a broad range of automotive and light truck cooling systems rather than being tied to a single OEM specification. Its borax-free, nitrate-free, and amine-free chemistry aligns with the inhibitor requirements of many modern vehicles, avoiding older additive packages that can conflict with newer system materials or seals.
These older inhibitor compounds can deposit on aluminum surfaces, degrade certain seals, and are increasingly incompatible with modern engine metallurgy - which is why many OEMs now specify nitrate- and amine-free coolants. A formula free of these additives helps prevent build-up and corrosion in contemporary cooling systems, extending both coolant and engine life.
TRUEGARD Global Antifreeze provides corrosion protection for brass, aluminum, steel, cast iron, copper, and solder - covering the full mix of metals typically present in automotive and light truck cooling systems, making it well suited for mixed-metal cooling circuits.
The product is specified for automotive and light truck engines. The listing does not claim coverage for diesel or heavy-duty equipment applications, so buyers with those needs should review the technical data sheet or contact Truegard directly to confirm compatibility before purchasing.
In its unused form, TRUEGARD Global Antifreeze is 100% biodegradable. However, once it has been used in a cooling system it may contain contaminants such as heavy metals and must be collected and disposed of in accordance with applicable local regulations - it should not be poured down drains or onto the ground.
