My car overheated and when we tried to put more coolant in it, it just drained out the bottom. It smoked like crazy right before breaking down.
You may have a leak in your radiator. If you poured more coolant into it and it came right back out a leak exists somewhere. If the leak is that fast, it should be obvious to the eye without having to perform a pressure test on the system. Try to determine where the coolant is coming from exactly. If assistance is needed enlist the help of a professional from YourMechanic to inspect and replace your radiator if necessary. The smoke may have been related to the engine or radiator over heating.
