Zerex G05 Antifreeze: OEM-Approved Heavy Duty Protection

Zerex G05 (zxg051) is a professional-grade, Hybrid Organic Acid Technology (HOAT) antifreeze/coolant formulated for both gasoline and diesel engines. This specialized formula is the factory-recommended chemistry for many Ford, Chrysler, and Mercedes-Benz vehicles, as well as heavy-duty equipment from John Deere and Cummins. By utilizing a combination of organic and inorganic inhibitors, Zerex G05 provides the rapid protection of silicates alongside the long-lasting benefits of organic acids, ensuring your entire cooling system remains free from rust and scale.

Cooling System Performance:

• HOAT formula provides a long service life of up to 5 years or 150,000 miles.
• Low-silicate, phosphate-free chemistry prevents deposit buildup and gelling.
• Protects all cooling system metals, including aluminum, from corrosion.
• High-quality defoamers protect water pumps from cavitation and erosion.
• Meets or exceeds rigorous OEM specifications for heavy-duty and passenger vehicles.

Maintaining the correct coolant chemistry is the most important factor in preventing engine overheating and internal damage. Zerex G05 features a high-purity formula that stabilizes the cooling system's pH levels, preventing the acidic environment that leads to radiator leaks and heater core failure. It is particularly effective at protecting wet-sleeve diesel engines from cylinder liner pitting. Whether you are maintaining a luxury sedan or a high-output diesel truck, Zerex G05 provides the specialized, heavy-duty protection required by the world's leading automotive manufacturers.
