2 degrees? When I lived in North Dakota we used to have to put cardboard or a blanket in front of the radiator to get the engine to warm up enough to get some heat when the outside temp was near zero. Since the engine is heating up, as evidenced by your description of the output from the heating vent, I’m incline dto suggest that the system is operating normally.
Or am I missing something? Darn it’s hard to write answers without being able to see the post I’m answering!
