Radiator Nipple

Hi,

I read with interest the details on installing a new radiator nipple since my 523 has developed a leak in the same area and needs replacement.

Unfortunately the BMW agents in New Zealand where I live have no reference to the part required P/N 99-00-0-003-352.

Can anyone identify where I may purcase the part.

Thankyou

Warren

That is the part number and I think they are available from any US dealer. You could try e-mailing one and see if they will ship to you. The part is only about $1 US.

Thankyou for your assistance, I have emailed an agent in California and I will see how get on.

Check your PM and let me know...

I've always heard that E39's had sensitive nipples

I have now made contact with an agent and they advise that they will not ship internationally.

So if anyone can help then very much appreciated...

Thanks

If you have aluminum fittings on your radiator and steel on the lines they will probably strip if you take them off(ask me how I know).

A claw type pickup tool is also a good thing to have around.

I recently replaced my radiator with a Behr OEM unit. It was immediately leaking from this nipple. (In fact, I thought it might be some sort of pressure relief valve) It turned out that the nipple had a crushed and torn rubber washer.

You will note that the nipple has a tri-pronged end that gets pushed into the radiator. It clips into place. In order to take out the "old" one, I put a 10mm socket into the upper radiator hose opening, and pushed it on to the "clipped" end to push it closed enough so that I could pry out the old one. I TIED A STRING TO THE SOCKET SO THAT IF I DROPPED THE SOCKET, IT WOULDN'T END UP AT THE BOTTOM OF THE RADIATOR. This worked flawlessly.

on the drivers side what about the lower nipple (the one that attaches to the hose that feeds the heat exchange unit on an automatic), elbow joint, I have a leak from there, is that removable? replaceable? anyone know? Help!

Thanks!

I realize this is an old thread ... but over here, we're trying to devise a method of non-destructive radiator nipple removal (particularly for jobs that only require the fan shroud to be removed).

I don't understand this method of using the 10mm socket.

Can someone who does understand it elaborate for us in the thread listed above?

I think I figured out the 10mm/9mm socket trick to remove the radiator nipple intact.

From my experiments today, it will be easy to use this trick (9mm worked best for me) to remove a BROKEN radiator nipple, with the broken half being removed intact (so that you don't have to worry about it floating around your cooling system passageways).

It's less obvious how to successfully use this trick to remove the ENTIRE nipple, intact.

But let's have the next person try it and let us know!
