Zerex G05 Phosphate Free Antifreeze/Coolant 1 Gallon

ZEREX G05 is the original chemistry approved by leading automakers such as Ford, Chrysler, and Mercedes-Benz for use in their newer automotive and diesel engines. Using Hybrid Organic Acid Technology (HOAT), this antifreeze/coolant combines the benefits of both conventional and organic acid-based chemistry to offer top-tier protection against rust and corrosion.

Featuring high-quality virgin ethylene glycol, ZEREX G05 provides unmatched freeze and boil over protection. Its hybrid organic acid corrosion inhibitor package safeguards engines from liner pitting and corrosion, ensuring unparalleled freeze protection and anti-boil performance that exceeds industry standards.

The Hybrid Organic Acid Technology present in ZEREX G05 fights against rust, scale, and corrosion while effectively protecting all cooling system metals, including aluminum. The inclusion of high-quality additives not only safeguards against leaks but also does not harm gaskets, hoses, plastics, or the original vehicle finish.

The yellow concentrate formula of ZEREX G05 should be mixed with clean tap water or demineralized water at various ratios depending on the temperature range: a 50/50 ratio for temperatures from -34 to 265F, 60/40 for -62 to 270F, and 70/30 for -84 to 267F.

Backed by a 5-year/150,000-mile guarantee, ZEREX G05 provides protection against engine failure caused by freeze-ups or boil-overs. Each batch undergoes rigorous testing in the lab and real-world fleet testing to ensure that car and truck owners can achieve optimal performance and extend the life of their engines.

Additionally, ZEREX G05 contains 30 – 50 ppm of denatonium benzoate, a bittering agent that further enhances its safety measures. With ZEREX G05, you can trust that your engine is well-protected and ready to perform at its best.
