I was having rad issues so I replaced the rad, put a 180 thermostat, and replaced hoses too. Right before the job I noticed my heater fan started making a "whirring" noise when on high and the air is only hot right for the initial blast and then goes luke warm right after. Both heater core hoses and are hot to the touch after a drive. I have noticed a girgling noise when I first put it in gear and drive away. Any body have any suggestions as to what is going on as the rain is here and winter will soon be upon us here in Canada so I need my heat! Thanks in advance fellow mopar nuts!
