Our 2000 Oldsmobile Silhouette was doing the same thing plus we'd get low coolant indicators every 3 or 4 weeks. I went nuts almost trying to find the leaking coolant. It turned out that it was misting it's way out of the intake manifold gasket located on the top of the engine on the drivers side. You might see a small puddle of coolant on top of the block. Apparently it's a common issue with those engines.

Your oil is probably leaking. If the car is old, then it's likely to be scrap!
If you mean engine coolant is getting into the car, the heater core is leaking coolant causing the coolant level to drop and that causes the engine to over heat.
Definitely a radiator hose leak or the rad leaking itself, check all hose connections and try to see where the leak is coming from.
If you have odors coming from the engine area you probably have something leaking be it oil, engine coolant or exhaust. If the engine is overheating, a radiator flush may or may not help because there are several reasons why it could be overheating. Take it to a trusted mechanic for diagnoses.
Head gasket is leaking
Heater core / hose leaking.
are the cooling fans coming on
I would pop the hood when the car is running and see where the smoke is coming from. My bet is oil or coolant leaking onto the exhaust manifold
Is your fan coming on?
Check the thermostat, it may be stuck in place.
your car is broken
