I have a 2003 Subaru Legacy that with heat set to max, the temp is just a little warm. The engine temp is in the middle and stays that way after engine warms up. I get cold air in the summer with the AC on but in the winter with heat it's not very warm even at max. When I purchased the car, it had a new radiator and thermostat put in along with head gaskets replaced so that part is all working well. I do hear some gurgling from the heater core infrequently. The coolant level is good. I felt the hoses going to the heater core and the upper one was warm, not hot, and the other felt air temp. Any suggestions?
