Hey,
I think my heater core might be plugged up with something or another. My heat was working before I decided to replace my thermostat. Now i'm thinking maybe I got air in my system (wouldnt surprise me). I read in the FSM that it says that ou can purge the air from the core. Any idea how i can do this? I am going to try flushing the radiator today (sooo cold outside.... ) Just want to get this guy cookin up heat soon. This morning I had to drive to work with the good majority of my windshield (on the inside) covered in ice. Thanks for the help

Andrew
