I take it you mean it smells like burnt antifreeze. Does your antifreeze level seem to be going down? Also is it really smoke or is it more of a steam?

Hey you may want to get a pressure tester for your coolant system and see if you can hear a hissing noise in your heater core area (inside your dash on the right side behind the glove box) if you are unsure. You may also be able to tell if it is that area by how heavy it is coming out of which vents.
