BMW F10 550i Expansion Overflow Bottle Tank Reservoir 7575577 OEM

BMW F10 550i Expansion Overflow Bottle Tank Reservoir — taken from a 2011–2016 BMW F10 550i that came through our Texas yard. The donor car had 98k miles on the clock. The photos show the exact item you will receive, not a stock picture.

The expansion tank holds the coolant reserve and its level sensor and cap set the system pressure. Cracks at the seams are a common failure.
