Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

The problem you are describing can be caused by either trapped air in the cooling system or a restriction in the heater core. I would start first with making sure you have good flow through the heater core and if so. Make sure you not have any trapped air in the cooling system.
