I had a leaking head gasket and figured that I didn't have heat because of the head gasket. I just replaced the head gasket, flushed the cooling system, new thermostat, flushed heater core. I have heat for a few seconds then it turns luke warm and then cold. I turn it off and back on a few minautes later and it's warm for a few seconds then cold again. What else could cause my heat for a second then nothing?
