BMW F86 X6M X6 Engine Motor Radiator Expansion Reservoir Tank 17138621092 OEM

BMW F86 X6M X6 Engine Motor Radiator Expansion Reservoir Tank — pulled from a 2014–2019 BMW F86 X6M at our yard in Kaufman, Texas. The donor car had 80k miles on the clock. What you see in the photos is the part that ships — no stock images.

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.
