PEAK Original Equipment Technology Blue Antifreeze + Coolant is formulated to match European OEM Si-HOAT specifications. The ethylene glycol–based formula combines high-quality organic and inorganic corrosion inhibitors to protect aluminum and mixed-metal cooling systems. This 50/50 prediluted ready-to-use jug eliminates mixing and is suitable for systems that specify a blue Si-HOAT coolant. The formula is free of nitrite, phosphate and amines to reduce deposits and extend component life. It meets ASTM D3306 and BS 6580 performance standards for European vehicle applications. With a complete flush and fill the coolant provides up to 150,000 miles or 5 years of service life. Color-coded packaging and label guidance simplify selecting the correct coolant for BMW, Mercedes and other European makes. Consistent inhibitor technology matches factory protection to minimize galvanic corrosion and cavitation damage. The jug’s 1 gallon capacity provides a full system top-up or partial service for most passenger vehicles. Professional-grade formulation supports reliable cooling system performance and reduces maintenance frequency.
