### ⭐⭐⭐⭐⭐ 







  
  
    Correct part, way cheaper than dealership
  

*by M***. on Reviewed in the United States 🇺🇸 on March 20, 2016*

First off, most diy postings say to do the transmission thermostat at the same time. I figured I would be the one to not break mine removing the expansion tank...yeah just buy the thermostat ahead of time. It is almost impossible not to break it now that I see where it is. The part is so brittle that it literally crumbled when I touched it. Now to the main review:The part fit exactly as expected. It felt as high quality or better than the stock part. Only advice is to make sure your hoses "click" back in place once you are done installing. The top hose connection looked on including the clip being set but it had a tiny leak that I had to clean up. After locating the leak I pushed on the hose one more time and it made a click sound. No more leak. That was my fault not the parts fault.

    works, but not perfect replacement for 2003 330i
  

*by V***E on Reviewed in the United States 🇺🇸 on January 17, 2018*

so far working ok, but not a perfect fit.  Had to trim off one of the hose connector tabs so the hose could slip on all the way.  Also, getting the bottom clip on took some elbow grease to get far enough down for the clip to clip.  This was replaced on a 2003 330i.  One odd problem now is that the water level indicator light comes on every now and then.  I'll try to replace the sensor with the original one and see if that helps.

*by K***C on Reviewed in the United States 🇺🇸 on August 21, 2015*

Seems to be a good fit on to the radiator and with the upper radiator hose, which is not always the case. It doesn't show it here, but it also came with a bleed screw already in place. NOTE: This is for a car with Manual Transmission. If you have an automatic, you will also want to get the Thremostat that sits in the bottom of this thing. They always come out in pieces.
