Antifreeze & Coolant Concentrate

Best Antifreeze Coolant Concentrate

Zerex G05 Antifreeze Coolant Concentrate is a high-performance yellow coolant designed to provide dependable freeze and anti-boil protection for compatible cars and trucks. Its advanced Hybrid Organic Acid Technology (HOAT) formula helps protect cooling system components while supporting reliable engine temperature management in a wide range of driving conditions.

The Zerex G05 formula is designed to fight rust, scale, and corrosion while protecting cooling system metals, including aluminum. High-quality additives also help protect against leaks without harming gaskets, hoses, plastics, or the vehicle’s original finish.

This product is supplied as a concentrated yellow antifreeze formula and must be properly mixed with clean tap water or demineralized water before use. A 50/50 mixture provides protection from approximately -34°F to 265°F. A 60/40 mixture provides protection from approximately -62°F to 270°F, while a 70/30 mixture provides protection from approximately -84°F to 267°F. Always follow the vehicle manufacturer’s recommended coolant concentration.

Zerex G05 provides a 5-year/150,000-mile guarantee against engine failure caused by freeze-ups or boil-overs when used according to the applicable recommendations. The coolant is batch-tested in the laboratory and fleet-tested in real-world conditions to help support consistent cooling system performance and maximize engine life.

The 1-gallon concentrate container is ideal for cooling system maintenance, flushing, refilling, and properly prepared top-offs. It also contains 30–50 ppm of Denatonium Benzoate as a bittering agent.

Before using this coolant, verify that Zerex G05 and its HOAT technology meet your vehicle’s required coolant specification. Always follow the owner’s manual for proper mixing ratios and service procedures.
