BMW E90 335i 128i 135i Radiator Coolant Tank Reservoir OEM

BMW E90 335i 128i 135i Radiator Coolant Tank Reservoir — pulled from a 2004–2010 BMW E90 335i at our yard in Kaufman, Texas. 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.
