What is normal temperature for a 2002 Chevy Cavalier to be running at parked and while driving.

Sounds like a leaking heater core. Your temperature is probably fine. You'll have to have your local mechanic replace it for you, which involves removing the glovebox and heater duct, replacing the heater core and inspecting all the hoses and replacing the anti-freeze. If it continues to leak, you will be low on coolant, possibly overheating your engine.

Do yourself a favor and take Tom's advice. I know that having a newborn baby is expensive BUT so is the prospective damage your facing. Your car is important now. You know, just incase. God Bless you and the treasure he has untrusted you with.

The temp is past the 195 zone which is right in the middle running at about 210-220. My antifreeze runs out really fast and I'm getting a sweet smell in the car and white smoke or steam coming from the vent not sure. It's a 2002 Chevy Cavalier 2.2 LS I would really like to give a wack at it myself just need to know what the problem might be exactly. I thought it might be the heater core but since my antifreeze has leaked out by the bottem right passenger side I wasn't sure if it needs a radiator flush/ pressure check to see if I may have a leak in the hose or Heater core problem. Any other possible prob it could be i just want to narrow down what it could be. thank you guys so much for the help and feed back.

You have all the classic signs of a leaking heater core. It's not a job you want to do yourself.
