O-Ring

I am trying to find a part, it is the O-ring that goes where the Radiator connects to the coolant res. 2001 330 Ci.

Does anyone know where I can get one? We've tried other O-rings but we just can't find one quite like this one which is broken.

In respect to what item? The radiator to mounting plate? The radiator to upper radiator hose? The expansion tank to the mounting plate? Do you have an automatic or manual?

It would be the expansion tank to the mounting plate. Automatic trans.

I am having the same leak that you are describing.

The parts you ordered go on the actual trans cooler for the two smaller outlets that come off of the cooler and click into the radiator bracket.

I have had no luck finding the o ring that we need, also my bracket looks like it is not clipped in right or it has seperated, so i am going to check some things. My only option may be to buy the entire bracket and put a new one in. But this morning i took a look quick because the car dumped alot of water due to the 8 degree weather and I had to zip tie the bracket to get a tighter seal which so far looks like it worked. I ordered an expansion tank too which I am going to put in and ill check everything while I am in the process of replacing that.

EEuroparts has is, free shipping and no tax over 50$.

But if you find the o ring please PM me about which one it is.

I think the o-ring comes with the expansion tank, so I might have to buy an expansion tank just to get the o-ring. wish I hadn't ordered this one, I paid for overnight shipping ;(

Oh man, I will check it out tomorrow when it comes but I think you are right, 14.5 mm is too small, I think this one we are looking for is more like 20.5 mm.

I will call the dealership tomorrow as well and see if they have one, if not I will just buy that bracket and replace mine.

I looked into all of this yesterday, I called the dealer and had the guy try to match this simple O-ring up to any other ones he could find and he couldn't match it.

I ordered the expansion tank and it has nothing to do with this peice, The transmission thermostate clicks into the bottom of the expansion tank, but other than that it doesn't affect this O-ring.

The only option is to buy the entire bracket, I put a zip tie on it to hold it together and so far it has not leaked yet. but its also 20 degrees and snowing outside so I had no choice. I did notice when I originally got the car and did the AC condenser, I had to pull the radiator and there was cilicone on this connection, and I thought about it and did not re-silicone it because I would rather buy a new part than have it glued.

If anyone!*! finds the corect O-ring to use, PLEASE post it up!

I just removed this o-ring from a new mounting plate and it is identical to the two ATF cooler o-rings (17 11 1 711 987) that go into the mounting plate. Amazing that the dealer did not know this.

THANK YOU!!!!!!!!

I'm going to pick up the o ring for the oil cooler on Monday when the dealer is open and make sure it is the same, and if it in fact is I'm going to install it. Isn't that the o ring that you had overnight shipped to you?

I think I have the same problem also, did the o ring fix it?
Do you have to pull the whole radiator to replace the O-ring?

For a 2003 330i with Automatic it shows as the same O ring as the trans cooler box uses. PN 17111711987 14.5mm x 2.5mm Number 2 in the diagram... Looks like you have to pull the radiator to fix this. ( I am just looking forward to this as a good way to spend my saturday... )

The O ring worked for our leak, and I didn't have to remove the radiator.

Hi Guys. We have the same problem with the leaking O ring.
You would think you would be able to buy the 17111711987 O ring on it's own, it's not as if they used that O ring only in the one place, you can actually find it in several different places and is used in a lot of the BMW models if not all, we don't have all the models down under like the USA has.
Can someone please let me know the measurements for that O ring.
I find that your local Caterpillar dealer has a huge array of O rings, Yellow=High temp & pressure, Black=standard O ring etc etc.
I know this because I worked at Hastings Deering (Caterpillar) as a senior parts interpreter for years.
They also have one of the best ranges of nuts and bolts, the have rolled treads for more strength, they also have graphite impregnated nuts so they don't seize up.
I hope your Caterpillar dealer has the O ring.
Cheers to all, Bill.

According to realoem and Luky's post #14 above, the o-ring (17111711987) dimensions are 14.5mm x 2.5mm. Unless you are a glutton for punishment, one does not have to remove the radiator to replace the o-ring on the connecting plate or the two O-rings on the auto tranny cooler that are attached to the connecting plate.
