[V8] Temp Sensor

[CoultL at aol.com]

I have already knocked out all of the obvious culprits.  The electric  fan 
fusible link is new and the fan runs through the 3 speeds correctly.  I  
installed a bracket to lock the belt driven fan's viscous clutch....so it is  pumping 
more air than a new tighter clutch would.  The radiator is a brand  new 
German one.  The temp never rises over 110 degrees.  It will  get there in hot stop 
and go with the AC on or off.  On hot days it  will go a little above 100 
while cruising on the highway.   Basically, it will get too hot unless the engine 
rpms are up.  It  seems like the water pump is not pumping enough water...but 
I am  thinking that the thermostat is just not fully opening.  We will see.   
I will hold off on a new temp sensor.  Thanks to everyone for the  advice.
