Formula G48 Coolant

The Genuine BMW Blue Coolant (part number 82141467704) is a factory-recommended antifreeze concentrate designed to ensure the proper function of your BMW's cooling system. This G48 formula, the familiar blue-colored coolant used since the 1990s, is specifically formulated for BMW/MINI cars and avoids nitrites, amines, phosphates, or borates. It is a hybrid formula that offers improved service life and is more environmentally friendly than other types. This coolant is non-diluted and must be mixed with distilled or demineralized water. A 50/50 mix is recommended for most environments, while a 60/40 mix is suggested for colder climates to prevent freezing. For enhanced corrosion resistance, anti-freeze protection, and water pump lubrication, a 1:1 ratio with distilled water is advised. For drivers seeking additional cooling properties in warmer climates, reducing the antifreeze concentration is possible, but it's crucial to measure the freezing point. The addition of Red Line Water Wetter is also an option for improved heat dissipation. It is important to note that this specific blue coolant formula is approved only for cars manufactured up to the 2018 model year. BMW introduced a new formula with silicate for 2018+ vehicles, offering better short-term corrosion protection. Therefore, the older blue formula is not recommended by BMW for cars produced after January 2018. Always use the recommended coolant for your specific BMW model to avoid compatibility issues.
