BMW's aren't cheap cars. They're an investment. And an investment demands careful maintenance and plenty of TLC. Ensuring you use the right kind of coolant on your Beemer is one of the cheapest and easiest ways of keeping it in tip-top shape. Coolant is a little miracle worker: it protects against corrosion, acts as an anti-freeze in winter, and assists in engine cooling in summer.
All cars need it, BMW's just as much as any other. But a BMW isn't your 'average' car, and its coolant needs are a little different from what you might be used to. Beemers need coolants that are free of nitrates and phosphates and that prevent the corrosion of aluminum components, not to mention a whole list of other things that make the job of choosing the right one a lot more challenging than you might think.
But don't panic. If studying the small print on the back of coolants is getting in the way of you and a good time, you've come to the right place. We've studied the labels, dug through the research, and read the reviews. In the process, we've found the five best types of BMW antifreeze on the market today. Without further ado, here they are.
