Sounds like a head gasket to me check the oil if it looks like chocolate milk then it's definitely a head gasket or you can also check your coolant and see if it has an oily residue on the top which is another sign that the head gasket is blown this is just the most common thing that would cause the problem you are having the only way to properly diagnose the problem would be to physically check it out myself or have a mechanic in your local area diagnose the problem just make sure they are reputable before taking your car to them
I don't know. this sounds serious. you do not want to damage your engine. a mechanic should inspect and offer suggestions. don't delay.
there may just be be a damaged or loose hose. when engine is cold make sure there is tension on the drive belt for the water pump. if possible, make sure the radiator is full and the radiator overflow reservoir is at the lower [ cold] line. if all seems OK, your engines thermostat may need to be replaced.

Sounds like Clutch in your fan
The coolant level is right on, no hoses are leaking and the accessory belt is intact. You start the engine, let it idle and make a visual inspection. There's no sign of belt slippage.
If your car is like most, the cooling fan is mounted to its drive pulley via a clutch. Clutch fans operate at different speeds under different conditions to help reduce drain on the engine and to save fuel. When the engine is hot, the clutch fan runs nearly as fast as the engine. When the engine is cold, the fan runs much more slowly.
The fan clutch operation is regulated by a valve that is opened and closed by a thermostatic spring. The valve controls the flow of a viscous silicone fluid between chambers in the clutch assembly. When the engine is cold, the clutch is essentially disengaged, which is why the fan runs at its slowest compared to the engine's speed. As the engine warms up, the air flowing to the fan assembly becomes hotter. The hotter air causes the thermostatic spring to unwind and open the valve. Silicone fluid from the reservoir chamber flows into the main chamber, engaging the clutch, and the fan spins faster (though it's still slightly slower than the engine.
Hope this helps!
SOURCE: Where is the thermostat located on a 2003 pontiac aztec?
grab hold of the upper radiator hose, and follow it back to the engine block. The housing the hose is attatched is where the thermostat is hiding :)

SOURCE: 2003 pontiac aztec wont shift out of park.
You have a few safety catches on there, one, the brake has to be on. It is a switch on the brake pedal, it goes directly to the shifter, a mechanical solenoid, pumps out a pin to prevent the car from going into gear without somebody driving. The second one is the same idea only it comes from the ignition switch, the key has to unlock the steering and the shifter. Also, if it parked up against a curb or something, it will be hard to get out of park. Hope this helps.
