It is available as a "repair nipple" with BMW part no. 17 11 0 419 132, by Behr. Really cheap, but sometimes a bit tricky to find. During replacement, don't worry if the bottom part of the old one snaps off and falls inside the radiator end tank. The new one just snaps in place.

How old and how many miles you have on your radiator? If its fairly new and that is the only defect you can purchase a 90 degree elbow fitting which is what appears to be leaking in that picture. If not swap the radiator.

That looks like the first sign of a cooling system overhaul in need!

Typing /nipple F3 gets this:
- Cooling system overhaul mishaps (broken radiator nipple) (crooked fan clutch nut) (broken bleeder screw) (thermostat loom misplaced) (broken expansion tank nipple & cn90 repair) (expansion tank fell apart inside)

When you re-attach the "curvy" overflow hose, make sure the hose clamp screw is on the side and not the top. When the fan shroud is installed, if the screw is on the top, it can put downward pressure on the nipple and cause it to leak.!

I wouldn't say it's safe to drive like this but manageable if the loss is small. But just from the picture no one can tell that because the coolant evaporates quickly. So this leak might be tiny or major.

The real danger is if it goes so low on coolant that some air gets into the inner circulation. So make sure the coolant level is o.k. And just because there is some coolant in the expansion tank it doesn't mean there is no air in the system. Be aware of any coolant level changes! Avoid long city driving, stop and go traffic.

I'm confused where you're coming from, and I don't know, offhand, what a "smarterchild" is, so I'll simply explain everyone helps in the way that they can; I try to answer the question with a link to the answer.
Hope that explanation helps.

Reason: It would improve the fan shroud removal DIY steps by eliminating the need to destroy the factory hose clamp.

DETAILS:
- One of the steps in the fan shroud removal process is destroying the factory clamp on the expansion tank overflow hose into the radiator nipple.
- Very often, this brittle nipple breaks off while you're manhandling the factory clamp (due both to age and poor design of the factory nipple)
- Even if the nipple doesn't break off, you now have to place a less-than-optimal clamp on the end of the hose securing it to the nipple
- If you put that clamp on wrong (see cn90 warnings), it will even interfere with the placement of the fan shroud

Caveat:
- Even with a feasible method of nipple removal, an old nipple might still be fragile and break, so always keep a spare on hand.

REQUEST:
- Can one of the brighter folks on this forum devise a method to remove the radiator nipple intact?

Excuse me? How was what I said negative? I just asked a question. SmarterChild was a robotic creatin on AOL instant messenger back in the early 2000s, whos responses were siri like if you know what i mean, I was joking. I dont know who you think you are. Do you always start your sentance's like that, in lower case. And your no grammer nazi, so nice try.

Of my 15 thousand posts, almost every one has a link. On purpose.

And, of my, oh, about 50 repairs and about 100 mistakes, almost every one has a DIY (or a how-not-to DIY). Again, by design.

So, to answer your question, the reason for the links is that I rebel against the posts which say 'do a search', just as I rebel against the "ask me why" without actually showing my own experience. So, I show people where to find the information they are asking about (rather than repeat the answers over and over again in each thread).

This is efficient, and helkful for all. It only takes a single click by you to see that.

Specifcially, one of those links above is a very detailed and very personal view of that radiator nipple, which, typically for my threads, includes photos, diagrams, part numbers, supplier prices, a DIY for removal, a DIY for replacement, and even autopsy photos from the INSIDE of the radiator, looking OUT to that nipple.

You see, if you look at my tagline, I like to add value - and my particular way of doing so is to supply a link to that value.

Hope that explanation helps.
Very much, I thought more people would know what smarterchild was. I never said that you didnt add value, you add much to this forum. My comment was more directed towards your replys are similer to a google search. That was my point. No harm intended.

I guess I misread your intent , for that I apologize. It seems like I wasn't the only one to read it that way. A "robotic cretin", sounds like a ramones song to me. Have a nice day.
