Well the hoses going in and out of the core are both the same temp, and also the same temp as the rad hose, So I would suspect the heater core is working fine. I'm going to go pick up a new thermostat today anyway, cheap and easy to check. Luckily its almost 10 degrees and only lightly snowing so won't be too bad to work on...
