Replaced the radiator, water pump, thermostat, and heater core and when i try to bleed the air out it seems to keep getting more air in it. When i try to drive it the temp will start to go up while cold air is coming out of the vents but then it will start to drop and i will have hot air from my heater again for just a minute then its cold again. Will the intake manifold gasket or head gasket cause this .
