Fits perfectly, move over your hoses and cap.

Good to refresh cooling system with changing expansion tank, they are known to crack and that may cause lot of problems.

part fit perfectly for my '06 530i e60 N52 setup

GREAT PRODUCT!!!

No issues with fitment.

Perfect price for the OEM brand expansion tank for cheaper than what BMW charges. These plastic tanks develop cracks and you get leaks when the Car is heated up. I recommend replacing this Coolant Tank before yours cracks abd leaves you stranded! Such a cheap price for some Peace of Mind!!

The part quality appears to be identical to the BMW Genuine part it is replacing. Fast delivery (ordered on Friday at 3:30pm and parts was at my home midday the following Tuesday with Shipping method: UPS® Ground [Best Value (62% OFF)] )

I ordered a new expansion tank mainly because the float stick was broken on my original one so it was hard to tell how much coolant was in my system. This expansion tank doesn't quite have the quality of the genuine tank but it serves its purpose and seems to work just like the original. Only different it has really is a cosmetic difference which is the top of the tank has more of a molded look and not as smooth as original one. The molded image of the coolant level guide isn't quite as clear. Other than that I am very satisfied and would highly recommend this part vs genuine if your trying to save money. Note: This part doesn't come with a new cap so be sure to order new cap if your in need of that as well.

Close to original but not quite 100% the same although works fine.

Great product, fits perfectly and the delivery method was next day delivery and in fact it arrived on time. I will recommend this part any time.
