Had this happen once. Found out the thermostat was'nt opening. Replaced it and everything worked fine. Watch your heat gauge, if after a few minutes of the engine running and the gauge goes from nothing to hot imediatly instead of gradully, you;ve probably got a bad thermostat.

What would cause smoke from the side of the radiator?

It is very doubtful that it is smoke. It is most likely steam. Either there is a pinhole leak in the radiator allowing hot coolant to escape that then vaporizes into steam when it hits the atmosphere... or there is something spilled on the radiator that steams when the radiator gets hot. Have the radiator pressure tested for leaks.

I have a 97 Dodge Stratus If your car ran hot after about two hours but did not read hot could it be the thermostat?

You say it's running hot, so i am assuming you have hot water in the radiator. If the thermostat was not opening, there would be no hot water in the radiator. Since the temperature sensor is on the engine, it reads the temp of the water in the engine. (Not in the radiator). The fact you have over heating tells me the water is getting hot but the sensor is not reflecting that. I would say it's either the sensor, or the gauge.
