Expansion Tanks

A BMW expansion tank ensures that your radiator is always full, even when cold, and provides a way for hot fluid to expand without releasing fluid on the road below you. Factory BMW tanks are made of plastic, and will eventually crack, leak and fail. BMW expansion tanks should be inspected during routine maintenance. We recommend replacing the expansion tank as a preventatively whenever you replace the radiator and coolant hoses. We also offer high-quality aluminum replacement tanks for some BMWs. Use our SEARCH BY MODEL feature to filter these items for your BMW.
