BMW Coolant Expansion Tanks for BMW X Series E70 (2007-2013)

Clear BMW chassis

Please ensure your correct model is selected

On certain models, namely E36, E46, and E90, the factory BMW expansion tank is prone to either breaking at connection points or blowing apart altogether. If you're starting to feel like your expansion tank is on borrowed time, it's probably time to replace with either a direct OE replacement, or strengthen your cooling setup with an aluminum expansion tank - we offer numerous performance upgrades for your expansion tank. Especially if you're someone who likes to track your BMW, we recommend upgrading your expansion tank to avoid ruining your track day.

The coolant expansion tank in your vehicle provides extra space for fluid expansion and contraction due to temperature changes. Because it regularly experiences these fluctuations, it can become prone to cracks or breaks over time. To ensure that all coolant remains within the system, it's important to replace the tank if it has been damaged, such as with cracks, broken nipples, or damaged mounting points.
