Greg:
I can't say much about a 66B; I have a 75B tourer. However, I can say,
it never overheats (touch wood). In fact, I have exactly the reverse
problem: it won't make the heater heat atall (despite a full tear-down
and rebuild of the unit last winter). I have the plastic fan,
water-pump driven, not the electric units. Temperature on the car hovers
just a little left of the N on the guage, most of the time. Every so
often, on very long sustained highway trips, it'll make it to just a
nudge past the right of the N. I never get anything but lukewarm air
from the heater ... new core, new temp sending unit, new t-stat, and
heater control valve working per specs. ::shrug:: I simply assume the
car's doing better than normal and stopped worrying about it a few
months ago. (Possibility it's because it's got a 75 water pump driven
fan on a 79 motor, but I've never really explored that one).
So, I suppose the answer would be 'no', they're not designed to overheat
... you've likely got a problem somewhere. I'd check the radiator and
hoses and see what you find.
