Well I can probably figure it out from this diagram. http://www.realoem.com/bmw/showparts...99&hg=17&fg=05
I might just bite the bullet and take it to aiken bimmerworks here in town and get it fixed.
I have a leak that starts leaking when the car is cold and then goes away. It is coming from the bottom of the expansion tank. I figured my sensor was bad so I replaced it yesterday. Well this morning I start my car and it is still leaking from down there. Anyone know what it could be? Can anyone explain how to remove the expansin tank. I have a felling it might be damaged. How , I don't know.

Okay it stopped leaking already. It drips for about 2-4 minutes at the most when cold and then it is fine. Something is expanding when it gets warm and stopping the leak.
leak should be either a gasket or a broken part. Doubt a broken part would fix under pressure, so, bet Gasket # 3 is loose or damaged.

Thanks. I wasn't thinking of pressure building up, just heat. I assume as more pressure builds it causes the gasket to tighten up. Well, I can't get that gasket on a sunday anywhere so I guess i'll have to wait till next weekend.
