I don't have any experience with the Behr radiators but I can't imagine
the radiator cooling so much that it affects the cabin heater.  The
thermostat would just be cycling closed more of the time if that were
the case.

I live in northern Maine and I drive my Vanagons year round.  I've
driven in -40 degree temperatures, at highway speeds,  with plenty of
cabin heat.

The first year I owned my '85 that wasn't the case as I learned that I
bought it with a bad thermostat.  That first winter I had to put
cardboard in front of the radiator just so the engine would operate
normally.  Replacing the thermostat cured that problem.

Is the 190 degrees (or so) (thermostatically controlled) a high enough temp that this would heat the interior the normal hot temp?  Could the source have a thermostat that is stuck wide open or a heater valve that wasn't opening completely? Am I making any sense?
