BMW Antifreeze Coolant 82141467704 - 1 Gallon

The BMW Antifreeze Coolant — 1 Gallon Pre-Mixed (Part No. 82141467704) is BMW's OEM blue coolant in a pre-mixed, ready-to-use 1-gallon format — the correct choice for a complete cooling system flush and refill on any BMW from the 1967 E9 through current production. Pre-mixed at the factory-correct 50/50 ratio with demineralized water, it eliminates the risk of incorrect dilution and is compatible with BMW's full historical model range.

Pre-Mixed vs. Concentrate — Which Do You Need?

For a cooling system flush and refill, the 1-gallon pre-mixed format is the practical choice — most BMW cooling systems hold 1.5–2.5 gallons, so two or three gallons covers a full flush without mixing. For top-ups and trunk emergency reserve, the 1-liter concentrate is more space-efficient. Never use tap water for dilution — always use distilled or demineralized water to avoid mineral deposit formation in BMW's precision-machined cooling passages.
