Lookon places like thermostate housieng or pipes at top of engine, get eth engine warme and here shold be screws that you can loosen to get rid of the air. It could bea n actuator in theheater tha isn't opening that waswhy I asked if both hoses are hot if they are then it's an actuator. In heater. They contorl direction and temp it could also be a vacuum leak if yours system is vacuum check for ahose off going to firewall or under heater control
