<< RE: Does the rear heater add to engine cooling?

I'll answer this from direct experience.  I had an '85 with cooling problems
(later replaced the radiator).  On summer trips on the highway, climbing
mountain passes, I had the rear heater open (and the front heater also) with the
fan on max for the extra cooling.  When I turned the rear fan and or the front
heater fan on to full blast you could see the temp level drop.  Kind of like
Feynman and the ice cubes, run the experiment and get the answer. >>

The only thing all this proves (?) is that a van will overheat with a junk
radiator hanging out front.
