RE: [Chrysler300] Heater valve question

["Bob Jasinski" <rpjasin@xxxxxxxxxxx>]

Jean-Yves,
 
The wire is a temperature sensing tube.  It senses the temperature of the
air flow over it and a fluid in the tube expands and contracts against a
bellows within the valve, and thus regulates the temperature by increasing
or decreasing the flow of hot coolant through the valve.  I believe it is
called a Bourdon tube.
 
I can only assume the replacement has somehow done away with the need for
the tube.  If I had a choice however, I would rebuild the original valve and
reuse it.  Perhaps the designer of the replacement thought the tube to be
unnecessary, but I prefer to defer to the original design myself.
 
In the owners manual for the '61 Chrysler, the temperature control lever is
compared to a thermostat used in a home.  That is, once set, it will
regulate a constant temperature.  The way I see the valve without the wire
is that it is used as a manual flow control valve without any automatic
regulation.  
 
Bob J

Hi All!
What is the purpose of the long copper wire with the coiled end that goes
from the heater valve (Ranko type H16) to the heater blower box on 60-64
non-air cars? Will the valve work without the copper wire? I have a brand
new valve but it doesn't have said copper wire and would like to know if it
will work. No #'s or inscription on the valve...
