Perfect fit for 2009 BMW X5 3.0 L
Perfect fit for 2009 BMW X5This worked great and fit perfectly. It was tight going into the engine block but a little coolant lubed it and it fit perfect. Great solution!

Fits BMW 2010 X5 N52 3.0i.
Fits great 2010 X5 3.0i. 135k Will probably have to cut the stainless steel factory band clamp off hose with diamond tip drill bit available HF. But you won't loose much coolant. Reccomend you have atleast 3 qts coolant to add at end. I replaced bolts 25 mm metric with higher grade 10.9 and hose clamp both from lowes. I did BMW electric water pump bleed after finished.

If your old coolant hose is still in good shape and just the plastic fell apart. Cut hose right behind the broken nipple and steel clamp, slide this bad boy into the hose, install, top off your coolant and done. Stupid easy.

Fits more than what is listed
I bought this for my 07 328xi (in line 6 - non turbo) and it fit perfectly. When searching for this part, nobody lists the 328 as a compatible fit, but it is compatible. Good quality! No leaks - Good to go!

The part I received was the worst part ,what was a simply upgrade became a two day repair. Until I got the correct part, I put a picture in review. I decided to go cheap and I got burn.The o-ring is like three times bigger than it should be, please save yourself some time. Part very poorly made.
