BMW Coolant Expansion Tanks for BMW G82 M4 S58 3.0L

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 a reservoir for excess fluid as it expands and contracts due to temperature changes. However, frequent exposure to these extreme fluctuations can cause the tank to crack or break over time. To maintain proper coolant levels within the cooling system, any damage to the tank—such as cracks, broken fittings, or damaged mounting points—requires immediate replacement.
