BMW Antifreeze Coolant Concentrate 82142209769 - 1 Liter

The BMW Antifreeze Coolant Concentrate — 1 Liter (Part No. 82142209769) is BMW's OEM "blue" coolant in a convenient 1-liter concentrate format — the factory-approved product for topping up, flushing, and refilling BMW cooling systems from the earliest E-series classics through current G-series models. At 50/50 dilution with distilled water it provides freeze protection to -34°F — mix at 60/40 for Colorado's coldest high-altitude conditions.

Why BMW Requires Its Own Coolant Specification

BMW engines use aluminum cylinder heads, aluminum radiators, and aluminum cooling system components that are highly sensitive to the inhibitor chemistry in coolant. Generic coolants — particularly those using silicate (OAT) or phosphate-based inhibitor packages — can react with BMW's aluminum alloys, causing corrosion of the water pump impeller, radiator core, and cylinder head passages. BMW's blue coolant uses a silicate-free, phosphate-free, nitrate-free inhibitor package (meets ASTM D3306) that is specifically formulated to protect BMW's mixed-metal cooling system without deposit formation.
