Temperature sensors

[Jeff Witwer <jwitwer@intellicorp.com>]

I have an 86 5kTQ and am trying to diagnose the erratic operation of my
temperature gauge.  There are 3 temperature sensors that screw into the
fitting to which the upper radiator hose is connected.  One of these is has
4 connectors and is located on the bottom of the housing.  I have replaced
this one, and it seems to have made no difference in the gauge operation.
I am not sure what it sensed, but I guess that replacement was wasted $.
The other two sensors are on the top and back of the fitting and have one
and two connectors respectively.  The pictures in Bentley do not show my
particular model and the dealer's exploded drawings do not clearly show
these sensors either.  Thanks.
