About this item

  • The OEM hose fitting is a known weak spot in the coolant system as it commonly cracks and leaks. Our upgraded water hose fitting is to replace the stock fitting with aluminum design that will never wear-out, crack or leak.
  • Advanced Material and Design:Made of Billet 6061 Aluminum instead of plastic,which is durable and wear-resistant. There are no sharp corners on this fitting so that the coolant will not be disrupted as it passes through.
  • Our aluminum fitting has a larger diameter than the OEM part which improves the coolant flow and cooling performance.
  • Direct fitment with no modification,easy installation. Simply remove the end of the hose from the plastic fitting and then the fitting from the head (hose does not need to be removed from the thermostat housing to do this). Then install the replacement fitting to the head and slide the hose and hose clamp over the fitting.
  • Specially designed for BMW 1 3 5 6 7 Z4 Series (Engine N52 N53 N54 and N51 3.0-litre).Please check the following description for detailed compatible vehicles.

This product fits perfectly on my 2006 BMW 330i. What a simple and cost effective upgrade over the original. No leaks or cracks now. Happy customer!

Ok so been working on just BMW's since 1987 so seen a few. My wife has an 07 525i and of course the plastic fitting just broke off. The factory BMW hose with fitting is way more expensive and will fail again and again unlike this aluminum fitting. I rarely endorse aftermarket parts specially for BMW's but this is an exception. This aluminum fitting eliminates the possibility of it ever breaking again and the part fits and works perfectly. Just remove two 10mm bolts and pull remaining pieces from inside head sealing area. Use remove original clamp and reinstall with new clamp. If you have never done this before don't worry, it is easy and probably will take no longer than 45 minutes. Note: If you don't the new part will not fit and will most likely have plastic pieces get caught up in the thermostat and water pump. So for the price and quality of this part it is in my opinion awesome!!! Hope this helps and thanks.Oh and yeah taking care of those pesky oil leaks now too!!!

The part itself is great has a nice finish and tight tolerances with a good o ring the clamp that comes with it sucks. Thats the only thing that stops it from a 5 star

If you have a BMW with this type of coolant flange, it is a must replace item and will last forever and wont leave ypu stranded. If your plastic flange is in pieces when you remove it make sure to clean out and account for all of the broken pieces. Very easy to install. The one I received didn't fit properly due to the supplied o ring which seemed like it was thicker on one side, I replaced it with an o ring that I had and it works perfectly.

Just like others warned, the o-ring is a little too big. Have to lube up the crap out of it and after about 30 min of playing around with it, I finally got it to go in correctly. After all that effort of finally getting it in, I find out the holes are off by a millimeter or 2, so the bolt has to go in at a weird angle to bolt up. I almost ended up stripping the thread and decided to just stop, take my losses and buy another brand instead to see if they designed the holes to match the OEM measurements instead. If you look closely at my pic, you'll see the holes are off by a millimeter or 2. Please don't strip the bolt. You're better off buying OEM brand instead!

I want to say that the material looks steardy and finish looks good, clamps was too long for my taste and had to use my own, shorter clamp.The O ring was tight to fit in block but w/ minor lube I bade it fit.After I fit it in I tried temp setting screws in and they were not going in straight. Looks like the holes had to be out at about 1,2 mm. I had to drive my car so I had to modify with Dremel the holes out ward till the holes align. Look at pics and you can see. I used mirror to take the pics. I knew that the integrity of material would not be compromised so I had no choice but to do it. My clamp looks better too. I’m sure you can cut it and make it look nice but mine was also a bit wider. I’m sure I’ll never have to do this clamp again and if I do, I know it will fit.
