Check the temperature of the hoses going into the heater core. They should be too hot to hold onto for more than a couple of seconds. If they are hot, you are having an issue with the air distribution in the plenum. If they are cold, try to bleed the cooling system with an air lift, these can be purchased through amazon or many discount tool vendors for less than $50. This system will pull all of the air out of the cooling system so that coolant can fill every void thus making it air pocket free.
