Man this coolant issues with E90 are devastating. I was replacing my oilfilter gasket, needed to remove the mikey mouse socket to uncrew the bottom bolt. The socket just broke in 10 pieces. I replaced the mickey mouse socket, than the plastic hose connector(A) from the cooler to the radiator leaked, replaced that one to. After that the O-ring of the hose attached underneath hose A leaked, replaced that one. After a few days low coolant level warning came on, searched for leaks and found out the radiator top attachment was cracked, replaced the radiator and the O-ring of the in and outlet hose. And now finnaly after 2 months of headache i finnaly fixed it. Such a good car but the pastioc parts are terrible.
I'm surprised this channel doesn't have more views/subs. High quality BMW videos compared to some of the more popular ones out there haha. All this stuff reminds me of my old 335i and I laughed at some of the aluminum upgrades and hoses in your unboxing video, since all that crap broke on me. I'm gonna buy a 335xi next year and will be doing all the preventative maintenance I learned from my old one right away. Keep it up and continue growing!
N54 weak spot, well probably everything except the engine block. I own a 2006 E92 335i coupe. I love it and also hate it. Always something to fix. Good video. I already replaced my top hose fitting to aluminium. I busted the bottom plastic Heater piping to water pump and header tank. Ready to pull half the front of the engine bay out to replace the part I got today. The joys.
Lol mine is exactly the same. Engine itself is as reliable as anything, absolutely bullet proof. Everything bolted to the engine? One disaster after another 😂 did this same replacement after my top fitting disintegrated and pumped coolant all over the road. Now if I can fix the mysterious squeaking noise I'll be 2 VANOS solenoids and 2 O2 sensors away from perfect shape... For now
Yes, list of things replaced as long as my arm. I just got a new transmission cooler, it is weeping coolant slightly. Just waiting on a plastic clip removal toolset to separate the trans oil lines. If your replacing the long lower hose from bottom of the coolant tank, to water pump, to trans cooler, to heating. With my new hose I bent open the factory press fitted clamps, carefully with a screwdriver to use my old section from the waterpump to header tank side. I used a hose clamp from the rubber to hard plastic part of the hose to re join (sits under the radiator on the crossmember) . The new aftermarket hose would not clip on to the waterpump, slightly different angle for connector clip and O ring to click on. Be aware of this. Easy mod and the new hose was only $80 posted@@helplmchoking
Same reason I have mine, stumbled on one in trade from a body shop owner who could fix mine easy but was giving up on bmw. These n54 are great motors if they didn't get overheated like this guys. 8:15
Thanks mate! I really love working on these cars, second to driving them. Hopefully people enjoy the content and learn something about how to fix their own car too!
Any hints on how to separate the hose from the old plastic flange ? Crushing it with pliers looks quite risky, even in this video I'm not sure that some small parts didn't go down the hose.
Cut the clamp with a Dremel, some cut the hose but I would not go that way. But please don’t crack it, take your time you already saving money doing it yourself
what size, type are the vacume hoses? I noticed it doesn't look like you put the heat shield back on the hoses. Do you have a good source for the hose material?
I love watching these BMW overhaul videos, but have no skills. I’d buy the car, all the parts, and fly up to help do the work and learn. Sound like a cool video series? Sounds like a good vacation to me. I’ve got my eye on an older v-8 X5, hit me up and let’s do this!
I'm getting my flange changed tomorrow. Mine has started to leak, is it common knowledge in garages they know how to prime the pump this way? Great video
I've seen people bleed the coolant with the cap open but I've heard BMW directs you to keep the cap on when running the bleed procedure. Idk though I think either is fine. I've always bled mine while closed.
I replaced this on my e90 I honestly thought that was pretty messed up it was a plastic housing replaced it with metal of course currently in e92 now tho
You didn't seem to measure and mix coolant 50/50 with water. Lubricant in the coolant is needed for the water pump to be properly lubed when operating. Gutsy move Maverick using that pressure washer!
QUESTION PLEASE. (Model: 2008 E90 N54 Dual Turbo Sedan) I just ordered a new hose that attaches to the Mickey Mouse part that you mention 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 you have. Phil
You can change the hose, but it comes with a plastic fitting which will break in the future. Best option is new hose with a new aluminum adapter at the same time! Thanks for watching :)
If you can get underneath the car, then yes but only replace with an OEM part, I would not trust any 3rd party with that plastic part. My OEM plastic part failed after 15 years.
Is it okay to run semi-cracked oil filter housing to thermostat hose? is there any way to prolong the life of those type of hoses without outright replacing them
If it's already semi-cracked, I wouldn't rely on it any longer! Only solution is replacement, but the machined aluminum fitting will never have that problem again!
Thank you so much Chris, I just had this happened to me. The engine overheated for like 2 miles and then I had the car towed. I got a "red" thermostat alert. The car went on limp mode, then it did shut down. The oil temperature was around like 270 when I stopped the car. I restarted the car no problem (was running rough) and I still had the coolant alert when I had to drive on the tow truck. Do you think my engine is screwed?
It happens, and once the water has spilled out, there's no way of cooling down the motor which is why it was still in limp mode for a while. I'd service the cooling system, maybe do the water pump and thermostat while you're at it, and you'll be back in business. These motors are resilient enough. Good luck!
@@TheBimmerBarn Hey Chris, I just did it. Actually, I changed the thermostat and the water pump a month ago. I went to Oreily and they had the metal flange. I did not remove the oil line or the fan. I went straight ghetto South Florida style. It was reallll pain in the ass dude. But the car is running fine now.
I have oil leaking now on top of the oil filter housing… Do you know why this is occurring after replacing the coolant flange? Any help would be appreciated
Not good to use just water as coolant as previously stated and is Walmart oil BMW approved? A n54 is fussy engine and needs decent oil 5w40 approved is a good start. From a BMW tech.
I agree! The walmart oil was just to top off before we did the oil pan and filled the car with BMW LL-01 approved oil, which is the best grade by BMW standards! And BMW coolant is the way to go! Thanks for watching :)
Honestly the LL01 isn't really a requirement if you are not doing the long oil intervals. I still do LL01 oil since I can find some cheap here. Also 0w-30, 5w-30, 0w-40 and 5w-40 are all approved oils weights for the N54.
Can you please tell me something If you a person never did this before Why why you let the video go fast I understand you don’t want to video to be too long, but it’s very important that we see every step
8:14 bro does all this, and other stuff he says, and it STILL starts like engine was on fire once. Have you done compression test or test oil for metal??? This ain't a mechanic special it's a drag race FAIL 🤣
Your killing your alternator by spraying degreaser on it, that stuff kills alternator coatings and causes shorts within the alternator. Next time cover the alternator before using degreaser, if you want to clean the alternator use low quality gas.
That aluminum is going to corrode quite quickly. I have seen many Rain aluminum parts corrode like pulleys, etc. Get it anodized instead. Also replacing braided vacuum like with regular rubber probably isn’t the way to go, I get it it’s expensive but the right to drive that BMW, don’t cheap out

Very well put together video. Good to see someone with the same passion for preventative maintenance on these cars. Goes a long ways.

YOU SHOULD HAVE SO MUCH MORE SUBSCRIBERS!
you actually know what your doing instead of driving yellow lambos with straight pipes

What if I accidentally let plastic fall down the hose?
Are these same repairs similar for e60s ?
I’m looking everywhere for the vacuum line replacement kit. Any idea where I can get that from aluminum flange ordered.
I'm getting my flange changed tomorrow. Mine has started to leak, is it common knowledge in garages they know how to prime the pump this way? Great video
Do I get the part number for 1st part
Love this video I'm having the same problem can you please let me now the part name or is it called Mackey mouse? Thanks
Part link in the description!
What specific problems did you have from pressure washing?
I've seen people bleed the coolant with the cap open but I've heard BMW directs you to keep the cap on when running the bleed procedure. Idk though I think either is fine. I've always bled mine while closed.
I like watching the water go "spew spew" when its bleeding the air out 😁
Yes technically that is correct and how i do it. BMW TIS workshop manual says to have it closed.
It's cap and bleed screw closed when doing the bleed cycle, bleed valve open when filling the coolant (not topping off)
I replaced and it’s still leaking
I replaced this on my e90 I honestly thought that was pretty messed up it was a plastic housing replaced it with metal of course currently in e92 now tho
You didn't seem to measure and mix coolant 50/50 with water. Lubricant in the coolant is needed for the water pump to be properly lubed when operating. Gutsy move Maverick using that pressure washer!
just a cost us5.00 dollars part but it will cause tow services once broken in driving
does the cylinder head to thermostat housing hose fail? i replaced the flangee with the aluminum but im thinking if i should replace the entire hose?
Thumbs up for Ace Ventura's "Like a glove" hahaha

The other end attaches to the water pump with a screwed hose clamp and you can't replace the hose without quite extensive work underneath the car.
Wouldnt it be easier to change the hose too??
You can change the hose, but it comes with a plastic fitting which will break in the future. Best option is new hose with a new aluminum adapter at the same time! Thanks for watching :)

Awesome show 👏..
Do you have to remove the fan and oil lines or was that just purely to get a decent camera shot?
Oil lined was for the shot, but you could probably leave the fan in there if you have small hands!
@@TheBimmerBarn thanks!
Hi there,
May I know which (mm) size those vacuum lines are of the watertank?
Thank you in advance
Greets from Belgium
They are 3mm inner diameter! Thanks for watching :)
Excellent 👌
I had one of these cars for 6 years, its also the reason i ended up with a BMW Sportbike i love BMW

@@samyb2834 Let's gooooo! Happy for you
Had this exact story happen to me last night. Hoping my engine is ok after I install the aluminum
Does this cause coolant to mix with oil?
No, but take a look at your oil filter stand gasket! Hope that helps
I have oil leaking now on top of the oil filter housing… Do you know why this is occurring after replacing the coolant flange? Any help would be appreciated
@@30guarino It's a common problem, you need to replace the oil filter housing gasket (OFHG). There are in fact two gaskets, replace both.

BMW + plastic engine parts = engineered obsolescence (pony up tons of money for parts or a new car).
