First check to make sure the thermostat is opening. You can do this by removing it and putting it in boiling water. If the thermostat is good, you likely have a bad head gasket or possibly a cracked cylinder head.
Hey Alexis,
Sounds like your thermostat is stuck.. they cause the symptoms you describe... they are inexpensive in replace,, Have your coolant system flushed and refilled with fresh antifreeze/coolant.

Only 2 parts remaining are the thermostat and waterpump. Always start with the thermostat when diagnosing an overheating problem. If the car is overheating constantly under all conditions and coolant is backing up into the reservoir, it's very likely to be the thermostat. If it only overheats at low speed or idling, it's more likely the waterpump.

thermostat should be replace on over heated engine, the spring loses tension, probaly not problem, most like head gasket if over heated severly, if you have a air pocket & wornt purge thats one sign,press test on cold engine let sit at start up run slightly rough may see & smell coolant at tail pipe, could also pull plugs may have one wet all crude checks, there is also chemical you put in coolant & use a a stripe for combustion I think napa or snap on sells, alsoyou could do tear down & inspection wish you luck not sure what engine or car you have grand am or grand prix my guess a GP with poss 3.4 more likely then 3800 engine

The head gasket has gone so pressure builds up in the cooling system and forces water out of the overflow
You need someone to take the head off , skim it and fit a new gasket

If it's overheating it will lose antifreeze.I would change the thermostat first and see it it solves the overheating problem if not then worry about the water pump. Thermostats are only $7-10.

Bad themostat, dirty radiator (the front of it), corroded interior core of the radiator, weakening water pump, bad radiator fan.....just to name a few. More than likely? Low antifreeze level, or the thermostat.
