I replaced the flange on my E92 with 130K miles two weeks ago. Funny how it looks fine on the outside but will fall apart as you pull it off, it rots from the inside out.
Hello Mr. Zeiten, Don't you open the purge screw beside the reservoir tap for the electrical pump test in order to take out any air through the cooling system ? Congrats and thank's in advance BimmerN53
HEY ZEITEN I have a couple questions in this order #1 I am replacing 328i 2008 UPPER RADIATOR HOSE..how do u remove the bottom HOSE on it and what is that hose called? #2 do i have to drain the entire antifreeze if Im replacing the upper radiator HOSe and the mickey mouse COOLANT FLANGE..FLANGE ONLY I GOT AN ALUMINUM ONE #3 My radiator fan is on as normal when i have my car ac on, but its hot here in Florida..my infrared said upper hose was 200 degrees and i dont see fan coming on when i shut car off and its still hot...what temp does it turn on??? Hope u can answer all three..thanks UR VIDEOS R AWESOME!!!
1) it’s a heater hose, removed just like any other coolant hose on bmw, release the clip 2) no, you can just empty expansion tank, that should minimize the spill 3) don’t overthink it, normal operating temperature is about 98-102 degrees C so about 200-215F
@@Zeiten OH THANKS so much for answering right away I love ur videos I learned so much from u !! On that bottom heater hose connected to the upper radiator hose E90, do u pull it straight off or twist?? and also, when u bleed COOLANT, do u OPEN or CLOSE the COOLANT TANK CAP??? and is a aluminum mickey mouse FLANGE OK to use ??..ty very very much awesome videos!!
Happy to help, all the bmw coolant hoses must be pulled straight, be very careful with upper radiator hose, coolant cap open, and aluminum flange is fine as long as you don’t damage o-ring during installation very common issue
Replaced this hose as part of a cooling system overhaul less than 2 years ago(less than 15k miles), and just realized it's leaking from the engine attachment(the oil filter housing is not leaking on it), looks like the mickey mouse/plastic piece is no longer flush toward the bottom. Any advice on what to do? Will it likely need to be replaced completely or is there a way to salvage the existing part. Any advice or tips for next time is appreciated!
Well there is a metal flange by uro parts i like sticking to plastic hose by rein. Manufacturing fails happen so it’s very possible you had a defective part from the start
i did the same to X5 E70 N51 the other day, but my Mcikey mouse seems extremely tight to push in even with lub. after I get it installed, fired up the engine, and leaks..... question, which mickey mouse did you get ? what type of O ring to get if I replace it ? can I use regular plumbing o brings ?
great dyi, did this today and ngl, this took few hours, it was hard to get down there and clamp was in angle which meets the control arm even with smallest wrench, eventually (after I was able to rescue my tools which felt down on engine cover) I was able witch just the socket apply enough force with hands so I turned the clamp just enough upwards so I could loosen it.. even the removing the hose took some time because it felt like it was glued there.. applying so much pressure felt like no good for thermostat and pump connections - everything is fragile after those years anyway I would strongly recommend to just get the plastic MM fitting to cyl head and cut the hose if it fine, and get new clamp on top part
Excellent info. QUESTION PLEASE: (I have a 2008 E90 Sedan 335XI, N54 engine)... Would this method be exactly the same for my 2008 E90 N54? Is there any way to detach the lower portion of the hose from underneath the car as I already have the bottom shield off my car. Note: My hose is very similar, but is a slightly different shape the way in bends, than the one you have. Thanks as always. Phil
@@Zeiten Thanks for the reply on a N54 type car. My battery is older and I don't own a battery pack. Can I bleed the coolant system with the car running the whole time. (Heater on full temp as you mentioned). If not....Do you start the engine while the system is still in the bleed mode procedure or stop the bleed cycle before starting the engine Thanks. Phil
HEY ZEITEN! Sorry to bother ..fast question ~~~I am replacing the collant temp sensor right above the mickey mouse flange..do i have to bleed the system if i dont drain anything and put the part in really fast? thanks
I’d say yes, but electric coolant pump bleeding in general is not that crucial compared to mechanical pump, in other words i’ve seen cars after major coolant system work done running just fine without bleeding at all (although i strongly advise to bleed the system every time when doing anything coolant related)
@@theme721 yep I confirm, that's what I used too Took me an hour just for that one particular hose ! Thanks for answering man I appreciate , I hope you have a good day
We got the new Mickey Mouse hose on and did the bleed sequence. Unfortunately, we have another leak now. Best I can tell it's one of those two short hoses (One short hose has a very slight elbow type bend and the other short hose is U shaped with a heat shield wrapped around it). Not sure what happened as it seems like a new leak. Perhaps from the repair (which is not really near that area) or maybe there was an air pocket in the system and one of those 2 hoses burst open. Thanks. Philip
im having trouble with the o-ring being to big? and cant get it flushed when instilling the new hose. what could i do? get a new oring? i tired to oil it with WD-40 but not luck.
thank u for all ur help..the upper radiator hose went on great but the aftermarket coolant flange was a bear..the oring was too big i think but finally got it..I need to bother you for another question.. MY pick( to remove radiator hose clamps) fell into the black plastic E90 right BELOW hinge for hood LATCH..I cant get it out..the hole is in between both kidney grills but I cant see the part or see any opening in this black plastic funnel-like piece where it fell..any ideas? I dont want it to pierce my radiator or ac condensor...hope u can help ty for the awesome videos!
Do I need to jack car up and reach the tstat hose clamp from the bottom? I took out coolant expansion, removed air duct, but I can’t get a tool on the bolt from the topside.
I need help with my bmw while i was driving it the coolant resevoir just exploded and all the coolant leaked out should o just get a new one amd replace it or should i replace anythimg else
@@Zeiten sorry to bother but I am reusing the old hose..I'm talking about the silver CLAMPS, not the quick connect s....so i need to get the crimp silver band off somehow..or can Ii cut hose below it..dont know if it will be too short then to reuse...,.the new flange comes with new clamp so that I get but not how to take off old clamp?? ..thanks
Currently doing this job as I type this. The O ring on the flange is slightly bigger, anyone have any suggestions on inserting it? I really have to push and I can only manage to get one side on but part of the gasket is out of the flange after it’s screwed back in.
@moisescardonajr388 doorman is garbage, is metal flange? You probably won’t find proper size o-ring, my recommendation is to replace a hose with rein or genuine

Thermostat to cylinder head

The general principle is the same although it’s not exactly the same process, still doable from the top and might be easier from the bottom
@@Zeiten Thanks for the information. Always appreciated. All the best.

Start the bleeding and start the car shortly after, you’ll be fine

Just finished this job on my 07 e90. Was pretty easy, but the hose clamp on the bottom was hard
I'm doing the same and I can't get the bottom hose out on the passenger side , it's taking my patience 😂 how did you do it ?
I have the exact same car and year than yours
@@upsidrive9513 a very long flat head

that is water pump area, it needs to be replaced anyway

Good information, camera was one of the worst I've seen
HELLO ZEN what do u use to LUBRICATE THE NEW RADAITOR ORINGS WITH????? THANKS ALSO ARE THE NEW ALUMINUM VALVE COVERS ANY GOOD?
Just coolant is a good lubricant, stay away from aluminum valve covers, awful fitment, bad design in general
thank u for all ur help..the upper radiator hose went on great but the aftermarket coolant flange was a bear..the oring was too big i think but finally got it..I need to bother you for another question..
MY pick( to remove radiator hose clamps) fell into the black plastic E90 right BELOW hinge for hood LATCH..I cant get it out..the hole is in between both kidney grills but I cant see the part or see any opening in this black plastic funnel-like piece where it fell..any ideas? I dont want it to pierce my radiator or ac condensor...hope u can help ty for the awesome videos!
What is the flow of the coolant in that hose? Mine was broken and some pieces missing so im thinking probably i have plastic pieces somewhere
where do the pieces go inside ur waterpump??
Do I need to jack car up and reach the tstat hose clamp from the bottom? I took out coolant expansion, removed air duct, but I can’t get a tool on the bolt from the topside.
On the 335i
Is it possible to work when the coolant is hot?
Possible but not recommended
while i have you..whats the diff between radiator fan switch in bottom E90 hose verses temp coolant sensor above mickey mouse flange?
Just different points of temperature measurements
I need help with my bmw while i was driving it the coolant resevoir just exploded and all the coolant leaked out should o just get a new one amd replace it or should i replace anythimg else
Start with expansion tank and see what happens, all other components might be fine or not, bleed the system and keep an eye on water pump
HOW DO U REMOVE THE SILVER CRIMP BANDS ON THE HOSE W/o cutting radiator hose????? THANKS
You don’t, those are quick connect hoses, pull metal bracket up and pull the hose
@@Zeiten sorry to bother but I am reusing the old hose..I'm talking about the silver CLAMPS, not the quick connect s....so i need to get the crimp silver band off somehow..or can Ii cut hose below it..dont know if it will be too short then to reuse...,.the new flange comes with new clamp so that I get but not how to take off old clamp?? ..thanks
Cut where it ends, should be enough you can’t remove it

Great video, but your camera man is really frustrating. Auto focus is not the way to go for these types of videos.
