I agree with Jim.....sounds like a fan problem
Had a very similar problem myself recently with my 90 water-cooled Carat.
My VW mechanic (Ken Nethkin in Fishersville, VA) replaced the sending unit
and it seemed to fix the problem initially (I could hear the fan come on).
However I was still unhappy with the temperature the van would run in
traffic so he actually replaced the thermostat in the engine....seems that
by default it was rated to keep the coolant in the engine till it reached
190 deg. So he swapped it out for a unit rated to 180 deg (kept the old one
to switch out if needs be during the winter). He also put a manual switch
in so I could engage the fan manually if I was getting a bit anxious in
traffic).
Ken Wilford has a quick and easy way to trouble shoot the radiator fan
system at

Best luck to your friends
