What is the screw called that is at the opposite side of the radiator hose?

I have a 2000 BMW 528i. I had a little leak on the coolant reservoir and every time the low coolant light comes on I just add more. So today it came on and I added so more again. When I came to a stop a notice that my car was smoking pretty bad, so I pulled over. Come to find out that a phillip like screw was spitting coolant at the opposite side of the radiator(on the radiator hose). So I went to tightened it with a quarter and found out that is was broken or melted already. So my question is what's the name of that part so I can order from BMW....Thanks!!!

try posting a pic... im not really sure what you are talking about, but if its the spout on the radiator thats broken then your just gonna need a while new radiator, sorry... unless its soo small that you can get a real good welder to fix it up if its a metal raditator...

I think you are refering to the plastic philips bleeder screw on top of the radiator. If that is broken.. then yes.. you will have a leak.. a rather large one.

In the above post he is refering to the imput neck... which is rather faulty on older radiators... it has a coolant hose attached to the radiator with a screw clamp... is the neck is broke.. new radiator...

Pics are a must if you want a good answer here.

I'm actually going to agree with alpine here, sounds like the bleeder screw (and it's a fairly common replacement item) Get a new one and make sure when you get it it has o-rings on it (I've gotten them without before so ALWAYS check) and you should be fine
