If you suspect a head gasket there is a test kit for about 40 bucks. There are good YouTube videos on how to do it. Scottykilmer.com has a good one. If you don't want to do it yourself, a lot of shops have a sniffer that they can use to see if there are combustion gasses in the radiator.

Sounds like you have air in the cooling system. Try bleeding it. HTH. -Jim

Could be the heater core, check for leakage inside and outside the car.
