Hello. A coolant leak can come from a number of places under the hood.

Typically, if it just started smoking all of a sudden, it is because a hose failed or the water pump is leaking. I typically get the vehicle in the air to inspect it for the leak. If it is not easy to see, I do a pressure test on the system to see if I can find the leak. Worst case scenario, dye can be added to find the leak.
