- Hey everybody! Today we will be looking at the notorious BMW coolant outlet flange failure (mickey mouse connector), this is very common as these cars start to age and is an issue among many BMW N5x N2x motors. In this video I replace mine in my N54 335i E90 with an aluminum replacement as part of preventative maintenance, and not a minute too soon! Check out the video to see just how bad yours can look and I urge everyone with the original plastic piece to please swap it out to an aluminum replacement ASAP!

I bought this on a video recommendation as preventative maintenance and mine was already cracked too just like yours. Was wondering how to properly remove from the hose. You answered that perfectly!
I'll be doing this job in a couple weeks. It's worth noting that if you buy a new hose assembly, it comes with the new plastic fitting installed, so you will have to remove the fitting either way. Thank goodness someone had the sense to make replacement aluminum fittings. BTW- I would have clocked that clamp differently so I could easily loosen it if needed in the future. Thanks for making this video. It is very comprehensive and clearly shot!
Awesome video. Very detailed. Mine broke off while driving, so tomorrow I will be replacing the flange and hoping the hose is good.
Really great video! Very well explained on how to replace it.
Great video and more detailed than most. It was quite hard to remove the metal clip on the coolant hose and crushing it with the Chanel Locks probably saved me a half hour in trying to cut it off. The O ring on the new device is not really compressible by hand and you have to thread the bolt to squeeze it in. My car was at 100k and it looked ok but it broke off pieces inside the hose that I had suck out with a wet dry vacuum. I needed about 1 litre to top it off after the bleed process. You can do a partial flush which is nice. Took me about 2 hours total but worth it.
Thank Goodness my coolant light went off and warned me that my coolant was low which inturn lead me to inspect my 2010 328i. My thermostat had cracked and it was leaking, as a result i changed water pump. Further inspection revealed 2 other hoses had to be replaced and of them was this crazy flange hose. Didn't even know this thing existed good thing i wasn't stranded. Good video.
this was super helpful. love the videos that come out of PD's shop. i have had my car worked on at your shop. great shop! i got a mosselman thermostat the other day. i might be giving you guys a call if i don't get around to installing it myself.
Definitely a good job to replace these. Mine was totally broken from inside (N53B30)
I siphoned all the coolant out of the expansion tank before starting (into empty 1 gallon coolant container, filled up about 80%) = zero leakage when I removed the plastic flange. I have a 2010 e91 with 47K miles and plastic fitting was still in perfect condition FWIW.
My 2006 e92 330i 120k had an oil cooler gasket leak (in front of the filter housing). I now have a coolant leak from this Mickey Mouse flange caused by the oil leak speeding up deterioration of the plastic. Was not looking forward to changing the whole hose as the bottom end is way down on the thermostat so difficult to get to. Hopefully this video has given me an easier fix although may have to remove the fan to get enough room to work. Many thanks for the video really clear !
Doing a Coolant change in the near future. Bought the replacement flange and coolant from FCPEuro because I found this video. Thank you
2014 428i N20 51000 miles
Thank you for the support! Best of luck with the service
Bro hot the same car and sameproblem
This just happened to me but mine broke completely off . thanks for the video
I'm getting mine done 2mo, is it common knowledge for mechanics to know about the process where you turn the blower on and foot on pedal for a few seconds? I'm worried the garage might not do this, but I don't want to tell them how to do their job lol. Great video man
Perfect video man !!! Mahaloz from Hawai’i!!!🤙🏾😎🏝️
This might be a dumb question but do you close the bleed valve before bleeding, or after the bleed cycle is done? I just want to be 100% certain lol.
Thanks man! Saved me $200 on labor
Hello Petrol Fed!
Your videos are very good and of great help to those who are professional or not.
I want to record my thanks to your noble person.
Now let's get to the topic of your video.
On my BMW M5 E60 LCI 530i - (N52B30A) 2008/9 I had to change it due to the time of use. It was still the original.
At the moment there was no substitute and import would take time. What did I do?
I took a connection and blue PPR tube (Random Polypropylene Copolymer), which is used in compressed air systems and made it similar to the original.
I'm using it even today, and the original that arrived I left it as a reserve.
It was very good and met the characteristics of use. It's been in use for over 6 months now.
Big hug from Brazil.
I followed the steps to bleed the system on a 2006 N52 and the heater didn't come on, and the water pump didn't come on either.
So I manually play with the bleeder with the cap off, car running, and warming up. And I'll bleed it some more with the cap on.
I've bled it this way before. It seemed fine. What's the issue if all the air doesn't come out, etc. ?
Thanks, the connector was toast.
Great video. I ordered one to replace when I swap out my oil filter housing gaskets. Kill three birds with one stone 👍🏼
Thanks for the videos
Just changed mine
Very helpful
Thanks for watching and glad to hear
Thank you very much for this excellent video.
Hi just curious if you know what the part is called that the fitting goes into that you were cleaning out? I’ve replaced the flange but the part is what’s causing a major coolant leak.. Thanks
Very good explaining bro
Mine cracked while trying to get to my oil filter housing gaskets. I appreciate the video.
Excellent info.
(I have a 2008 E90 335XI, N54 engine)...
Would you have a video of how to change that complete hose. My hose has a leak down low (there's a small hole in the rubber hose about 12" down) and I am trying to find a video on what needs to be done to detach the lower part of the leaking hose and reattach the new hose. Thanks in advance.

is the water pump usually loud like that? i have a n55 and my water pump sounds like that and i thought its because its failing
Good video! That’s funny I’m union pipe fitter we call them Chanel locks too lol
In aviation, we call them boar-hogs. The term seems to come from the military.
I did this yesterday on my '08 E90 190k. It was very easy to do. The plastic fitting came out without breaking, but I was able to break it off easily, which makes removing the original crimped hose clamp easy.
Hi, what were the symptoms that caused you to change it?
@@divakim206 No symptoms. Read online about the weakness. Easy job.
@@rhollyday ok thank you.
Hi, in 2008 bmw x3 i see tge same steam coming out but the temp gauage is normal and not rising, i dont see any temperature gauge pin moving towards red, also the radiator fan doesnt turn on while steam is coming, tried with bmw standard bleed procedure i dont see any coolant coming to reservoir tank, also i see the engine oil i coulnt see any milk color or coolant mixed with the engine oil nor i see any leak outside . any suggestions
great video. thanks. I wonder why there is only two bolts for that flange. leaves a potential failure point on the other side. maybe o-ring covers that?
Yes the O ring handles the sealing part well, the bolts just ensure the flange won’t back out. You’re right though it is interesting that they never added a 3rd bolt to be safe
All because BMW used plastic. So many critical parts made from plastic. They know plastic parts make BMW unreliable. Well, it last until after the warranty period. LOL
You got any video changing that hose?
Is that the lower radiator hose?
Is the F56 mini using this too?
Would this also work for an 04 545i??
2016 BMW X1 coolant is leaking behind engine oil cooler. It's not leaking for a few days and suddenly flushes out everything. Any ideas?
Now once your done with this repair, don't forget to top the coolant off, then turn on the car. Have the heater on blast, heat all the way up. Take the coolant cap off, and wait until your radiator fan turns on. The coolant will burp air out...(Watch your eyes)... then top off your coolant again... and keep the car running still.
Mom just got a used 2009 528 and that flange sprung a leak, but I caught the evidence in the morning puddle underneath. But in taking it apart did not expect a 1/8 inch sliver piece to go down the tube toward the pump. My reaction was to plunge the tube downward and fluid gushed out but later when we kept back together there was the clicking sound which tells me evidently the plastic went into the pump fan. So now I would assume to change the pump or rebuild the pump?
Given then notoriety these water pumps have for failing I would just replace the water pump, not rebuild it. And a new thermostat while you’re there. Sorry to hear about the situation!
Great video! I better check mine and replace it. thanks
What year is your car and how many mileage thanks.
Thank you for a great video.
I have 2011 535i, drove 9 miles back home in the middle of this trip, temperate went up to 260F, wanted to come back home asap. 30 fit to my driveway car did not accelerate. Opened a hood and realized the coolant hose flange broke off and all my coolant was gone. Do you think the engine is dead?
I don’t believe the motor is damaged in your case, but yes it is a slight possibility. Considering it was not that many miles the car probably went into Limp mode when it got too hot and cut power/acceleration on purpose to prevent further damage to the motor. Try changing out the flange and refilling with coolant, and try driving it again. Don’t forget to bleed it too as lot’s of air probably got into your cooling system.
Clean engine. Good video. Good to go!
what tool did you use to get under the old clamp and pull it off the hose? super helpful video thanks! :)
They are called long reach angled needle nose pliers, and thank you!
great video..when u bleed the coolant do u have to open the bleed screw on resivoir tank ? and the cap removed or closed when bleeding on resivoir tank? thanks great video
Before filling the reservoir with coolant I undo the bleeder screw to let air from the system escape as I fill it with coolant, then once the reservoir is full I close the bleeder screw and I leave the cap off and begin the electronic water pump bleeding process and watch for air pockets from the stream shown in the video. Alternatively you can rest the cap on top without screwing it on to prevent splatter. Either way once there are no more air pockets (usually 10min) you can run the car, just make sure to fully thread the cap back on. Thanks for watching!
@@SpeedCave GREAT ty awesome video any other way to get that crimped metal silver hose band off?
Thanks, I got to do this on mine...😀👍
What about any debri that fell down the hose? Would you have to completely take the hose off? I think some debri fell down mine.
I just pointed it downwards to allow coolant to run out and flush out any small pieces. But if you’re unsure that would be a good idea
Just did this last night and it was pretty bad @75k I recommend doing thissss
The Mickey 🐭 flang yeah I need an aluminum one today
Thank you 👍🏻
What was the mileage on this car?
Wow thank you for this video. Really helped me with the install
Awesome 👏🏾
We’re I can found or buy the piece of metal and skip the original.
I think BMW recommends tightening the cap and screw while bleeding the system. Then eventually, air will come on top and coolant level go down . Then after bleeding you add more coolant to the required level
Thanks for the video. BMW shop wants to charge me 1400 dollars to do this
That’s crazy
Great video, thanks. Approximately how long does it take to fully bleed?
Thank you! And right around 10 min usually
@@SpeedCave cheers
That coolant pump draws a fair amount of current. It's a good idea to hook up a charger to your battery that's capable of 10 amps or so.
Istg im in love with this bmw the day i saw it on ig plz post more on yt
Thanks so much! Definitely have some more videos planned, getting Pure Stage Stage 2 turbos, Titanium inlets, relocating coolant tank and a bunch more!
RpleX Plays they done forgot about us the last of the fully aspirated & true 6 cylinder bmws I hope they forever make parts for the guys who love their cars I hope the water pumps they now make for e90s have longer lifespans & they need to revise the fuel pressure regulator develops a inevitable crack right at the top that stinks your car with gas after about 13 to 14 years
@@rudeboi9625 yup that same crack happened to mine last year haha. Had to replace the whole sending unit.
Make sure you don't over tighten the bolts left bolt stripped on me , I'm sealing the whole thing with sealant and cleaning the inside again and lock tightening the new bolt that stripped .my mistake was tightening everything too tight . When bolt starts to turn turn turn try my method
Great video thanks
Thank you!
I am about to do this. I have watched many videos but none say if u have to drain ur coolant before u start or just take hose off and top off with coolant??
The whole process is as it is seen in the video, no prior draining needed, whatever leaks out from the hose gets replaced when you top off
This is the same problem on my bmw 530i. I have to find someone to replace it for me at my home cause I’m not able to drive it anywhere with it overheating.
You made this look easy. Can’t get mine to go in on my 2007 328i.
Have you tried wetting the rubber O ring? It should help it slide in smoothly. If not then try to work it in slowly up and down, hope this helps
@@SpeedCave I’ve tried it all lol. But it looks like maybe I might have the wrong o ring. Mine looks like it’s thicker and sits higher than yours. 🤷🏻♂️
Bro I’m trying to do this rn and it ain’t going on. Pissing me off
Lol me too and now I got the Rein flange, had to use a rubber hammer on both to get it in.
It won’t go in by your hand pushing it in, put it in its place put the bolts in tighten them by hand just enough to hold before you tighten the bolts and wrenching the bolts it will force it in and will work like a charm.
anybody else have trouble removing the fitting from the hose? i tried channel locks it’s not doing much 😭
what skirts do you have, do they just attach to the factory panels?
These ones are from KG Splitters on Instagram! Just uses self tapping screws to attach
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.
Phil
Hello, the hose attaches to the coolant thermostat. Thank you for the support and feedback!
@@SpeedCave Hello...and thanks.
Sorry, I meant what does it attach to on the other end of the hose. (Down low when it disappears towards the bottom of engine bay). What does it attach to down there? Thanks very much for any info you could share.
Phil
Yes the bottom of the hose would be the thermostat
@@SpeedCave OK..I see. I guess I was thinking old school when the thermostat was on the top of the engine block. Makes sense because the water pump is down low on this N54 engine.
Hopefully, it's not too hard to get to the hose clamp where the thermostat is located so I can replace the hose. Thanks again.
Before you out hose on make sure metal flange is on tight then put hose on allows you to tighten the two bolts perfectly straight .
I literally had this happen to me today thank god I was just sitting in the driveway and not driving but the aluminum head cost me $11 on amazon
Don’t you think that coolent that you bump is going to ruin the belts
I dropped the plastic from inside down the hose like a quarter of it. How can i get it out without taking hose off?
Safest thing to do is remove the hose and clear it out. You could try to point it down and flush it out best as possible but just removing the hose is not much harder to do
The coolant leaking out won’t damage the car?
I filled my coolant after installing the flange so that stick came up to full. Bleeding the system now and the stick dropped down to low. Is this normal or do I need to top off? Thanks
Yes that’s normal! The bleeding process gets air bubbles and air pockets out of the system which will take more coolant from the reservoir into the system. Just top off until it’s full again after bleeding
@@SpeedCave thanks man!
Es correcto como lo hace y la parte en aluminio es Mejor que la toma plástica.
Am i the only one who doesnt have 10mm bolts. Mine are torque bolts, would anyone happen to know what size? N26 2014
Is there a risk of problems to the serpentine belt from the coolant that leaks out during this process?
You can definitely go the extra step and clean the belt off with Simple Green or some kind of cleaning spray, even finish it off with belt conditioner if you wish, but from my experience it doesn’t negatively affect the belt if you don’t clean it.
@@SpeedCave Thank you!
I just replaced mine also but my engine light came on. Any reason why that might be?
Double check nothing was left unplugged or disconnected. If all is well then pull the code up, if you don’t have a scanner most auto parts stores can pull codes for free.
getting that part now can literally see coolant spraying out
Good luck on the install! If you are interested the part is sold on our website as well, link in description
@@SpeedCave say it fits for 535xi well see
Hi. Where do I get the alum. part (Micky mouse flange) pls?
I got mine from FCP Euro!
Does it make any other BMW owners (mine 06 525xi) angry that BMW seems intent on making a once great brand into a glob of crap plastic parts and then just slap a BMW rondell on it and then call it good??? Im waiting for a class action suit to replace all of the plastic coolant parts that are curiously softened by the actual coolant.....look it up.
Just to tell everyone I have 170 .000 km on my 2009 323! And I removed it and it's perfect!! I 🤔 think in some point bmw fixed these issues without telling anyone! Factory fix plastics I think 🤔 just like the water pump too anyways I changed it out to aluminum one since it was done and dropped 2L of blue fluid if I could show you picks of it I would by the way the band holding it on is stainless steel I drumeled it off slowly it's impossible to cut other wise.
Bro thank you so much!!! I thought I needed to replace the hose. & getting to the bottom of the hose is a bitch.
me too
This stopped the car from overheating? I replaced the hoses already
This stopped the coolant leak. My car was never overheating.
Another great bit of German engineering not, lets use a plastic fitting bolted to the front of the engine and them constantly flow boiling water through it, I had mine go (on a 523i M sport touring) in the middle of the night on a motorway, at first when I spoke to a UK dealer they said the part didn't exist, then they said they could get it but only complete with the hose for just under 100 pounds but it would take 2-3 weeks, I found one made out of billet aluminium (not unlike the one in the video) on ebay for less than ten pounds and had it within 3 days. these videos are great but they do show how bad and how much of a rip off the dealers are.
Please tell me yall seen all that coolant left on the pully:(
Will not buy another BMW = (Big Money Waste)!!! Too many plastic parts! Thanks for the video though!!!
What side skirts are those?
KG Splitters on Instagram! He finishes them in any vinyl finish you want. Black, gloss black, carbon look, etc. Good material and lightweight. They were my favorite non-carbon fiber side skirts I found
I couldn't push it. I just put the bolts and as I was doing so, the seal broke and the bolt snapped which half stuck in the head 😢😢😢. I cleaned it very well and lubricated with oil but no luck.
Sorry to hear you had trouble with the install, it is worth noting there are several aluminum flanges available on the Internet, and some of them are known to have issues inserting into the motor due to the wrong O-ring size. The best fitting option by far is from Rein Automotive part number CHC 0609
@@SpeedCave any tip how can I take the snapped bolt? No head .
You will most likely need an extractor set, where you drill into the broken bolt and use a reverse drillbit to grab it and spin it out. You can sometimes borrow one for free at local auto stores like AutoZone or O’Reilly’s if they offer that, or just purchase a decent quality one from Amazon. Worst case have it towed to a local shop that can extract it
Hi there, does this fit on N46 E90, 320i 2011 models as well?
Hello, this part does not apply to those engines as they use a different type of plastic hose fitting
@@SpeedCave Thank you for the feedback. Do you know whats the coolant hoses called that connects to plastic flange on N46 E90 as there's 2 pipes and mine seems to have some corrosion on the slimmer pipe since that flange connector has 2 outlets.
@@AvenNaidoo-qj4oh Yes that plastic flange should be BMW Part # 11 53 7 560 130 however please double check fitment to your exact vehicle as there may be different variants. This motor is not in the US so my familiarity with them is very limited.
@@SpeedCave Awesome, thanks for trying to assist. Will double check here in SA.
do you have to drain the coolant or is isnt necessary
About less than half the coolant in the system drains out, so not a total coolant flush just partial.
@@SpeedCave will it be okey to led it drain from the flange hose itself when disconnecting it. coolant recently topped up so dont really want to get under and drain it out.
i will do it tommorrow
i did but its leaking at the bottom of the flange
could you please provide a FCP part #? Thanks
CRP-CHC0609 is FCP Euro’s SKU number. You can also google “Coolant Flange FCP Euro” into Google search and it’ll be the first result!
@@SpeedCave THANKYOU
What the part number for the flange
Here is the part number if you get Rein Automotive brand: CHC 0609
Can it fit for a 328i
Yessir it will fit assuming it’s 2006 or higher
why on earth would you not invert the hose when removing the old flange and risk the chance of falling back down the hose??
The hose still has coolant in it and flushes anything you might miss right out when pointed down after flange removal, as we did right after.
Just shake the hose and push coolant out a few times make sure .
Bleeding the system for this?
Yup it’s a required step to get any air pockets out of the system, walkthrough is at 10:42
I just cut it because this hose is longer enough.
Link to ur toolset up tho?🤣
how many miles is on this car and what year is it?
2009 335i and this was done at roughly 115,000 miles
at what point do you think this should be done as a maintenance item? mileage/ years?
@@raybutts9133 hard to say since every car goes through different heat cycles, not to mention it may have been replaced at some point during the cars life without the owner even knowing. For example if a shop does your Oil Filter Housing Gasket and they break this flange in the process (which is very common in less experienced shops), they will have to replace the flange/hose. But regardless it’s a safe bet to just change it since plastic will inevitably fail, aluminum will not. Can’t even count how many cars have been towed to our shop because of this plastic part’s failure!
@@SpeedCave Thankyou for taking the time to reply to me. I have a 2011 BMW 528i with only 3500 miles on it that I have owned since new. As you can see I dont drive it much. I was a little concerned about "age" (11 years)??
@@raybutts9133 wow that is extremely low mileage! Congrats on maintaining such a gem, that is very uncommon. As for the age of the plastic, while it definitely has not gone through as much wear and tear as a higher mileage vehicle, it might still be a good idea to do this upgrade preventatively!
And buddy your car is a e90 but I love it
Yeah it sounds like I said E93 at the end but I said E90 335i really fast, sorry for the confusion lol
That part is a automatic tow.
wow. another classic "WTF was BMW thinking" design?
Probably should have mounted the flange first, then put on the hose.
Factory flange comes pre-attached so it is normal to install the flange with the hose already on it. As well as when you use this style clamp the two 10mm bolts will interfere or get in the way as it’s a very tight spot to fit pliers!
@@SpeedCave yeah, no. I’ve done this repair on an x5. Mount the flange and slide up the hose clamp with channel locks. Also, easier access to the bolts without a hose in the way.
@@speedster0009 To each their own!
