A leak from your expansion tank can quickly turn into a major problem. The BMW plastic cooling components for the E82 128i/135i, E9X 325i/328i/330i/335i, and E89 Z4 have a tendency to leak along existing seams. Heat cycles and exposure to the elements can take their toll on any plastic component. While there is no replacement interval for these, we do encourage you to proactively replace cooling system components before a problem might develop.

Fits all models with N51/N52 non-turbo and N54 twin-turbo engine.

This Genuine BMW Expansion Tank comes complete with the internal coolant level sensor. There are previous versions of this tank with part numbers 17137607482, 17137567462, and 17137519368. This new number replaces them all.
 
Fitment Note: not for models with N55 Engine
