Zerex G05: OEM-Approved Hybrid Organic Acid Technology for Peak Thermal Management

Zerex G05 Antifreeze/Coolant (Formula 861583) is a professional-grade, low-silicate, phosphate-free chemistry designed for both gasoline and diesel engines. Utilizing Hybrid Organic Acid Technology (HOAT), this formulation combines the rapid-acting protection of traditional silicates with the long-lasting defense of organic acids. It is specifically engineered to meet the stringent requirements of global manufacturers, providing a neutral pH balance that prevents the degradation of aluminum components and high-strength alloys found in modern cooling systems.

Features

• HOAT Chemistry: Provides a robust protective layer on metal surfaces to prevent cavitation, erosion, and scale buildup in high-heat zones.
• Extended Service Life: Formulated to provide up to 5 years or 150,000 miles of protection, reducing maintenance frequency and long-term costs.
• Corrosion Inhibitors: Contains high-quality defoamers and bitrex to protect the water pump, radiator, and heater core from internal oxidation.
• Global Compatibility: Meets or exceeds major OEM specifications including Chrysler MS-9769, Ford WSS-M97B51-L1, and Mercedes-Benz 325.0.
• Temperature Stability: Engineered to provide freeze protection down to $-37°C$ and boil-over protection up to $+129°C$ at a $50/50$ concentration.

Choosing Zerex G05 ensures your vehicle operates within its designed thermal parameters, even under heavy towing or extreme idling conditions. Its technical reliability makes it the preferred choice for heavy-duty applications and passenger vehicles requiring a phosphate-free, long-life coolant solution.
