Change This On Your BMW Before Its Too Late! DIY Install

- In this video I show you how to replace a very common and often forgotten coolant fitting on your N series BMW engine. This procedure would be similar on all N5X series 6 cylinder engines and N2X 4 cylinder gasoline engines.
This would most certainly leave you on the side of the road if it fails. The factory pieces is made out of plastic and the upgraded piece I install is made out of aluminum and will not fail in the future.
You can purchase the fitting here (affiliate):

As always TOP END content! You're my N54 DIY hero! I bought this from ECS recently as well. When I do my cooling system rebuild, which includes all the hoses and other fun parts, this is included! You always make the mechanicals look so easy (and the camera work too!). Thank you again for posting. #weltspeed
Great tip, my first N54 is only in the 60k’s but I’ll be doing this at some point, your channel has made N54 ownership much more enjoyable. It’s an amazing engine and has made me into a convert. Keep up the good work.
If anybody is wondering it's called a "Coolant Hose Flange"
Thanks
I had this done at a BMW garage a few days ago. I bought the piece myself, a silver aluminium version, and they installed it. Very happy I did initiate this upgrade.
I love that you make videos like this, so I can help myself out to be prepared for things my 335i might do/need. Keep up the great work!!
Excellent videos I really appreciate you posting these. They add value and helped me with my 335i which I love.
Got that on my car. Works good. Thanks for the videos. You helped me fix so much stuff on my car.
Thanks for this my N55 Guru! Started out with the oil service which led me to replacing both the oil filter housing and the cooler gasket. Once there i noticed how much oil had leaked over time and built up over this exact hose and connection. I wasn’t about to put all the pieces back on only to do it again two days later. Thankfully ECS Tuning shipped the billet replacement next day air so the X5 wasn’t down for long. Man once those 10mm bolts were off I began to loosen the hose and the plastic broke exactly like yours did. Used your ignition coils and spark plug video to close it all out. Thanks again!
Great video! Thanks a lot. Just an FYI for all my e82 n54 guys out there. I managed to do this install without removing the radiator fan. It’s a little trickier but was well worth it for me saving the time taking the fan out. 👍
Mine failed last year. I was working on an oil leak When i noticed the coolant leak. I replaced with oem but i am going to do this mod asap. Trying to remove as much plastic from under the hood as possible. Keep up the good work
Thank you! Your videos are great and have saved me so much time, money, and heartache. Keep up the great work!
Man your vids are gold - thank you sir!
Mine broke while installing my inlets a few weeks ago. Did the ECS piece with the silicone hose. Appreciate all your videos.
Happy to see another vid! Hate to say it but I look forward to your car breaking 🤣 You have the best how-to's!
Haha when something goes wrong I don't get too upset about it, more easy content.
Thanks for the diy's. Because of one of your videos on the oil cap I found that the place where I changed my oil didn't place that middle peice back in to the filter. Whi h was causing my engine to act with the same symptoms you provided. Big thanks!
This jjust happened to my N53. Was hoping it was this simple :) Thanks!
Thank you for this video. I def need to do this. I was looking into buying a new hose but this is better. Thanks
Thank you for the heads up! Ordering part as we speak
Needed this video 4 months ago!
Of course this would happen when I was away for work and my wife was driving my car. The plastic fitting sheared off while she was driving; coolant/steam everywhere, so she pulled over and shut off the car immediately. Fortunately no damage, but this prompted me to replaced every damn coolant hose in the car (~100,000 miles / 160,000 kms) just in case any more plastic fittings decided they'd break as well. Definitely worth it for the piece of mind.
I refreshed hoses last year and doing this felt so good. that one spot was starting to give a little tiny leak. But I also had little leaks in a few places, radiator, DCT cooler hose. Many hoses and o-rings to deal with every 100k or so.
Mine failed 2 weeks ago, I was freaking out I didn’t know what it was😂 there was an excessive amount of smoke coming out my hood…. Crazy how I came across this vid just now. This is spot on! I will fail and you will be left stranded.
Oh wow yet another part to add to my lovely n54 maintenance wishlist 🤪 lol thanks for the info as always!
I did mine with just taking off the snorkel in 10 minutes. Be careful getting the piece out of the hose end and it breaking off down into the hose. The metal strap won't give so squeeze the other side to trap and pieces.
@@TheFrenchPug oh nice, appreciate the info!
Awesome content 🤜🏼🤛🏼
Excellent job 👍
I did mine today. At 92, 000 mine was all broken like yours. Thank you for some awesome DIY’s! You should host a yearly get together, on a single topic. IE: turbo upgrade. Maybe not.
I just DIY my coolant hose connector and thank goodness I did it as preventive because it was on its way out. Thanks
It’s funny how this happened to me last night.. great timing world and thank you for the diy info!!
Np! Hopefully you can get your hands on an upgraded aluminum one quickly and get your car back on the road. This seems like pretty common failure on any inline BMW engine from the last 15 years. Hence the reason for the dramatic title, hoping a lot of people see this and can change it before being stuck on the side of the road.
Smh, it happened to me 3 hours before the video was uploaded
@@VehicularDIY is aluminium better then?

Happened to me yesterday driving over the mountains
Another Great one!
Yep, it will happen, mine did while preparing to leave Walmart in the parking lot, had to get a tow, but I wish I knew about this piece prior to purchasing a new hose, next coolant drain I’ll replace it. Thanks for the tip🦾🦾🦾
Same here xdxd
But i replacing the whole housing in the parking area
I replaced this when I did a mishimoto oil cooler retro fit setup on my 2007 335i, it’s a super easy job it takes 5 minutes
Lol omg i found your site yesterday for replacing my ignition coils and spark plugs. Completed that job this morning and took it for a test drive. I came back from the test drive to pick up my wife and as i parked the car i noticed no power steering. As i looked into it closer this part you are showing was dripping coolant🤦♂️. The timing of subscribing is co-incidentally incredible timing👍
Hey Wayne. Curious, what did this have to do with no power steering?? Thanx
@@ralphrotten what i found was the coolant leak caused the serpentine belt to slip off the sheaves
@@waynemoffatt8683 Thanx!!
+1, my broke a while ago. Similar part is available from Rein I believe and available in Oreillys. If yours broke and you need one ASAP you can get it there. Bought mine there when I needed it ASAP
1000% changed this, it’s a super easy job and super cheap. Mine actually went out while I was driving normal.
Yeah my clickbait title is actually not an exaggeration here lol.
Probably most cars have used these plastic pieces for decades now. I had a 90’s VW Corrado VR6 which used a plastic coupling also. I changed mine to a metal after market coupler. I had an BMW 325is, I think 2000 Model. Changed out the water pump with the plastic impeller to a metal one. That is a must change on probably all cars I would think today. When the plastic fins break off the water pump with age, they go into the engine. A costly problem fishing those pieces out of the motor.
100% agree do this DIY ASAP!
Absolutely fabulous info! Thank you so much!!!!!!!
Glad it was helpful!
My brothers cracked while he was on the freeway, luckily car went into limp mode and prevented any damage. Replaced it with a billet piece and it's been fine ever since.
Thank you for this video though honestly
Damn! If I had only known this 4 days ago. The fitting failed on my E53 in the middle of nowhere. The tow was the expensive component of the repair!!! Have ordered a metal replacement for the newly installed plastic fitting. Lesson learnt!
hah wish I knew this when I replaced the factory pipe that broke at that fitting 4 months ago! 113k, unreal that yours made it till 200k.
Hi Sir, love watching your DIY videos! wanna ask how to remove/cut the fixed metal ring without damaging the hose and plastic/stock coolant flange?
Every time I watch one of your videos I call my mechanic the next day and he already knows exactly what I want done , I guess because a bunch of N54 owners in my area watch your videos too and call the same mechanic for a quote , in the last few months alone I changed my ignition coils from Bosh to Eldor and changed my spark plugs to NGK , I hope parts companies or Amazon are paying you because you're giving them a lot of business .
You get a small affiliate kickback.
Mine was exactly the same at 160,000 klm.
It looked ok but when I removed it the plastic was all decayed.
Highly recommended to replace this, it's cheap and easy work.
awesome ! im around 107,000 kilometers on my e90 will probrbaly do this sooN! thanks!
Getting one tomorrow !!!!!!!
I recently did an entire radiator and coolant hose refresh on my N52 with 172K. I used the aluminum flanged FCP hose for this problem area. The flange is already band clamped to the hose. It’s a quality part compared to stock.
After removing every hose, some had some more life in them, and some did not. The driver side top radiator hose plastic was in bad shape. Also the o-ring on the metal pipe going into the lower block was flat and not pliable. Just a matter of time before that failed, as well.
Replacing every hose is not easy on these motors. But neither is being stranded on the side of the road. I refreshed everything for peace of mind. If you have a high mileage car and intend to keep it, I’d recommend spending the $450ish in parts and refresh the whole system while you have it drained and apart.
so good 👍
Thanks for the great tip. I got our n54 yesterday(e93 2009) and it's only on 50k miles. So maybe I can wait some time before changing this part. Dutch regards, Nico.
It's not the miles that degrades BMWs plastic. It's the time.
Thanks to remember me to do it on my BMW X3 I’m going to it now thanks bro
Out of Toronto Canada love your videos bro
I just did it two weeks ago while I’m doing my OFHG, yours doesn’t look as bad as mine and mine only got 135k on it
A must do replacement.
A perfect time to block-off the non-functioning CAI ducting.
You definitely want to tackle this before it starts coming apart, I’ve found bits in the water pump from a fitting that looked just like this one when removed. Also check the coolant cap as it also seems to turn from black to brown and starts coming apart. And while I haven’t seen the upper Rad house fail, it starts to discolor as well so that would be a good swap out on a high mileage engine. This is the hottest part of the circuit and these parts definitely do not hold up nearly as well as the rest of the system due to it. I would think 100k is a about the absolute most you would want to leave these if you don’t want them to start shedding pieces. N55 has the same set up too. Great vid!
Thanks for the tips! Yeah all the inline engines from the last 15 years or so have a similar setup.
Anche su M54
It's funny, this was literally one of the first things I bought for my car two years ago.
Now I'm chasing down a coolant leak from my upgraded twins... weeee.
I had to do this also. I found out when I was changing the rubber seal for the oil filter housing. *Because the oil filter housing seal also leaks after 100K miles.
While changing it, I had to remove the water connector and quickly found out this is broken. A quick search on the community and learn that this is a common failure and also found the cheapest replacement part is made of CNC aluminium from Ebay.
This makes me wonder why the hell BMW made it out of cheap plastic???
BMW ownership is one of great pleasure and nasty surprise.
I had to replace this part very early in my 640i (N55) ownership with a billet one. Coolant was spewing all over like a water fountain. Since then, no more issues in that area of the engine.
Nice, if it were to let go I'd be worried about coolant getting on the belt and it coming undone and getting sucked into the front crank seal.
@@VehicularDIY Fortunately that didn't happen to me because I noticed the coolant leaking right after starting the car after changing the oil filter housing gasket. Whew!
hello how did u remove the SILVER HOSE BAND on the radiator hose..did u cut BELOW it? and then put on ur new clamp? great video thanks
I had the original plastic part implode during regular light driving. I was stranded, massive mess, sent plastic bits everywhere.
$10 at Amazon, 5 minutes to install. This is truly a no brainer- definitely replace the plastic version with an aluminum one if you have an n52.
Great video as usual. This is the best channel for N54 in my opinion!!!
Do you need to drain the coolant in order to change this or even if it isn't drained this is as much coolant that will come out of it?
No need to drain the coolant, you'll only lose about 1.5 liters of coolant. Top up with 50/50 mix and the car will bleed itself within about 30 seconds on startup.
QUESTION PLEASE. (Model: 2008 E90 N54 Dual Turbo Sedan)
I just ordered a new hose that attaches to the flange part that you replaced in your video. (My hose has a leak down low in the engine bay).
What does the other end of that hose attach to?
I cannot see where it terminates on the other end down low in the engine bay, even with the mud shield removed very hard to see. I wanted to plan this out before I actually do the work.
Thanks very much and great videos on your channel.

I've always had bmws, I work for bmw and even i keep a 85 piece tool set, a torx screwdriver set, and a small jack in my trunk for these situations lol 😆
I have this part sitting in the trunk of my 335i since June. I should get to doing it before it fails! Got the tip from seeing it on FCP Euro's blog. Good video as always! Would like to see you putting blue BMW coolant in though 😎. The outrage!
Haha I've been running G05 coolant since I got this car and have had it for almost 6 years. I've never touched the water pump, I'm starting to think it could be helping prolong the life of it.
My neck hairs stood up when it wasn't blue. Glysantin lists G48 for BMW:
www.glysantin.de/en/zulassungslisten
I've been using Zerex G05 which is a high end coolant and meets the spec.
@@VehicularDIY I haven't heard of it before! Do you prefer Zerex or just don't have access to the BMW coolant?
Its readily available nearby and slightly cheaper and I've never had to touch my water pump in the 6 years of owning this car. I think I prefer it at this point lol.
lol. I had a ghost coolant leak for a month or two until I discovered this part a couple years ago.
I change that when I replace major coolant hoses at 100K miles. It's always brittle at that time.
Just a heads up, ECS tunings ultimate cooling kit comes with this part ( at least for the 535I kit ). On top of upgrading nearly every weak point of the cooling system ( aluminum drain plugs, aluminized water pump hose, silicon rad hoses etc). hell of a deal for under 600 considering it also takes care of the maintenance pieces as well. I just finished this kit and its very thorough.
I may look into getting that thanks.
@@VehicularDIY Its not under the normal cooling area for some reason, you have to search "assembled by ECS" on their website in the search bar, and then you can narrow down for which car > cooling > then it should show up as the ultimate water pump and thermostat kit. Cheers, hopefully you guys find it, and don't buy just the OEM kit that's the same price with no upgraded parts.
Ya I was looking into this kit as well, but this piece is $40 as sold by them. ECS can sell you individual parts from kits if you wanted and can source other parts for less + warranty too. I am not seeing any functionality differences between any of these adapters either.
Wow, that's a great recommendation. Looks a little tricky though. Could I do the same thing to my 2011 328i N52 automatic? It has around 62,000 miles
Question please, this applies only for N54 engine? Or I should do the same on my M47? Thank you in advance.
I have two basset’s absolutely love them talking
Thanks
I'm getting the 2021 BMW G82 M4 ( to drive in West Los Angeles) ...............I'm wondering is this part on a replacement schedule? Such as, after a certain number of miles _____ x part should be replace?
I did this last year, when I replaced my oil filter housing gasket.
I got the aluminum one from Amazon.
Always making me buy stuff lol
Hello Friend, good to chat with you. Could you remember how much coolant was necessary to complete the cooling? Thank you.
I changed the water pump and thermostat not too long ago on my F15 but left this alone. I thought about it but was nervous about wrecking the hose trying to get the clamp off the mickey mouse fitting. Can you clip the metal clamp off easily without wrecking the hose? There's nothing wrong with mine so I don't think it would break off from the hose as easily as yours
do you also recommended for S55 engines? thanks
Do they make these for X5? I can't seem to find it , they only have aluminum..
Any other plastic parts you suggest replacing?
A great time to do this is when you do the OFHG. I got mine from ECS tuning
Oil Housing Gasket ? F ?
@@cp_pdn oil filter housing gasket
REIN makes a similar aluminum part (FCP Euro). The spring clamp is more of the cheap type...so get a worm gear hose clamp. Coolant flange issue also effects F30 N55 engines. Look for hose damage on the end.
Getting the old clamp off it a pain, since it needs to be cut off. You might literally need the jaws of life. The best option is to crush the plastic crusty coolant flange. (Hammer/Mallet or Channel Locks or Vise Grips). You might need to Dremel the plastic from the inside out (ID), not the metal clamp in (OD). Give it to a 7 year old. They know how to break stuff quick.
Bmw: ultimate driving machine
Also BMW: ultimate plastic failure machines
My friend has an '05 545i, almost the whole cooling hose assembly (it's a separate assembly of 3 interconnected hoses) failed within 3 days of itself. The plastic connection from 2 ends failed with somehow the last connection still in good condition, but it ended up with a loss of about 5 gallons of coolant and like 3 gallons of distilled water. This was on the n62 v8, and I think I'm going to be the angry owner of an n54 later this week with more separate cooling hoses. Wish me luck!
They're like Barbie Jeeps anymore :)
Hi do I have to remove the fan on my 2011 n55 e92 335i to get to the two bolts on the flange or can I reach them with leaving the fan connected ?
HI mate , is this same for N47N [2011] engine also ?
Interesting how yours is black, the one I ordered from FCP Euro and installed on my n54 was just the brushed finish. Also I believe it is very unnecessary to remove the fan since I did mine with ease with it in.
Dude this piece is a must replace. It broke in my N52 and I had in mind at the time to replace it preventively. It’s worth every penny to replace before hand because if it breaks you’re stranded, there’s no way you can get that hose back in place and a tow truck will cost more than 10 times what this piece is worth!! Wild that bmw cheaped out on a piece the aftermarket can produce to sell for 15 bucks they could have made it themselves for way cheaper and put a metal one there..
Yeah 100% I'm surprised I hadn't heard about this upgrade all these years. Hence the dramatic title lol.
@Laurence Cursaro gm has a piece that joins all the hoses in the cooling system and the thermostat which is made out of plastic for their 4 cylinder engines and it’s a lot worse than this
I mean BMW's quality is worse than Hyundai as a Fact these days? Who ever thought this would happen?
@Laurence Cursaro that’s why my 2006 325i is currently at 254k miles and has only needed regular servicing aswell as stuff that all cars will need as they age; hoses gaskets etc.
Mine failed last winter and it wasn't any fun being stuck in the fast lane during rush hour in Dallas. I've since changed over to that billet inlet.
Yeah it's such a simple thing that could really leave you stranded. Hence I don't feel bad about using such a dramatic title, trying to get as many people to proactively replace this as possible.
Is this for all bmws or? I have a 2007 320d 175bhp coupe
Does the N55 engine have the same issue?
200k, wow, you definately dodged a grenade!
fyi
same thing for anyone owning X3's too - replace them! 👍
What size clamp did you use?
Is there a part number on ecs for this 🤔
Schwaben makes a coolant evacuation tool which is very usefull when pressurizing and filling up the system correctly. It found a leak where I didnt install the oring correctly on the coolant fitting. Around 100k I replaced alot of the coolant hoses, radiator even cracked and leaked. Rein makes an aluminum fitting with hose instead of the plastic. Love my 07 328i but being proactive i probably dropped 3k so I can make it to 200,000.
This is AWESOME, Are there any other parts that can be upgraded from the cheap BMW plastic?
No that I know of but worth researching
Vargas Turbo Technologies makes an entire kit for the main coolant hoses that changes them from that brittle plastic fiberglass to billet aluminum and silicone hoses
Interesting, nice to have that option.
My friend has an 08 535xi with the same plastic part, I've tried to remove one from the parts car and the part broke. He ended up getting a metal one and it had been great ever since.
Nice video. I have F10 535i (N55 engine), but the install should be similar. Just wondering, have you considered getting a QuickJack system?
I have yeah, they seem to be coming down in price also.
One of my bolts snapped for the fitting while tightening. Any recommendations on how to remove. Luckily the fitting was pressed in tight and doesn't leak but only one bolt holding it.
You could try an easy out extractor but you'd need to remove that fitting to do it.
mine broke too, any recommendations for nice hoses we can use as replacements?
I have seen silicone upgraded hoses available from VTT.
E46 18 years old, 162,000 miles. I’ve had the car 14 years.NO FAILURES YET !!!!!
Can anyone tell me what tools are needed?
lol that happened to me last year while i was changing the the oil housing gasket and the cooler housing gaskets because i had to remove the hose and it came apart the same way lol
Yeah luckily not while driving
