Zerex HT-12 Antifreeze: OEM-Approved Green Formulation for BMW Systems

Zerex HT-12 Green is a premium, long-life coolant specifically engineered to meet the stringent BMW LC-18 specification. This advanced formulation utilizes Si-OAT (Silicated Organic Acid Technology) to provide exceptional protection for modern engine cooling systems containing aluminum and light-alloy components. As an OEM-approved fluid (BMW 83-19-2-468-442), it ensures compatibility with all factory seals and gaskets while providing the thermal stability required by high-performance European engines.

Features

• OEM Compatibility: Officially approved for BMW vehicles requiring the HT-12/LC-18 specification, ensuring no risk of chemical reaction with factory fluids.
• Si-OAT Chemistry: Combines the benefits of organic acids with silicates for rapid passivation of metal surfaces against corrosion.
• Phosphate-Free Formula: Prevents scale buildup and hard-water deposits, maintaining optimal heat transfer efficiency.
• Extreme Thermal Range: Protects against freezing in winter conditions and prevents boil-over during high-load summer operation.
• Extended Service Life: Designed to provide up to 5 years or 150,000 miles of protection without degrading the cooling system’s integrity.

Using Zerex HT-12 is critical for maintaining the warranty and cooling efficiency of your BMW. Its precise chemical balance prevents cavitation and erosion of the water pump, ensuring the long-term reliability of your engine’s thermal management system.
