Coolant Expansion Tank, Aftermarket - F22 M235i, F87 M2 N55, F3X 328d/335i/435i

New coolant expansion tank for F22 M235i, F87 M2 (N55), F3X 328d/335i/435i.

It is very common for this expansion tank to get brittle and crack over time, leaking coolant, causing overheating, and potentially stranding you on the side of the road. The constant hot/cold temperatures and positive pressure of the cooling system stress the plastic until eventually a crack develops. If you are replacing any other part of the cooling system we suggest inspecting and replacing this tank as a preventative measure.

This part is manufactured by an aftermarket supplier of European auto parts, including many cooling components. While not carrying OEM status, this part follows the design of the original very closely and uses similar materials. An aftermarket part may even have the same TUV approval as its OEM counterpart. The brand may even be OEM to another manufacturer besides BMW. This aftermarket brand has a two year warranty - the same as Genuine BMW and OEM brands.
