Hi I have a 03 grand am and it just started to over heat while I was driving and leaks coolant out of the over flow in the coolant tank, I changed the water pump and thermostat but still no luck, when I start the car it idels rough for a short time (30 sec) I also have no heat in my car, could this be a head gasket? Or is air getting into my system some how? Thanks

Could be just condensation for a cold engine after the engine is fully warmed-up and still smell like coolant -could be a blown headgasket, cracked head or block
