Losing anti-freeze somewhere, help!
I have a 1999 Pontiac Grand Am. Every couple of days I have to put in anti-freeze. I park it and can't see any spots on the ground. The radiator looks good, all the radiator hoses are dry, even the ones going into the heater. When I drive it to work, I can see smoke coming out from the grill, but nothing is dripping under the car, that I can see. It seem to be wet behind the pullies and the long pully belt. Is there something behind these pullies, a by-pass hose or something? I can let the car idle and see nothing. It seems like I lose it while I'm driving and it's under high pressure. Any ideas?

Park it on a clean piece of cardboard immediately after driving it and see if there is any coolant on the cardboard after sitting overnight. Also, look at the exhaust when it's running, it will be white if coolant is leaking into the combustion chambers.

3.1/3.4 LIM gasket, known problem with these engines, GM is on their 3rd type of gasket now, a little better than the others, but still not a "fix". You can do it yourself, all day job, but not unmanagable.
