BMW E88 128i 135i Radiator Coolant Tank Reservoir OEM

BMW E88 128i 135i Radiator Coolant Tank Reservoir — taken from a 2008–2013 BMW E88 128i that came through our Texas yard. The donor car had 95k miles on the clock. The pictures are of the actual part in stock, so you can judge it before you buy.

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.
