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!!!
