[DeTomaso] Odd problem

Chris,
The fan sensors are located in the radiator. If the T stat is stuck closed the hot coolant is trapped in the engine and does not make it to the radiator and sensors, thus no fan.

The gauge going to the block was reading higher than it normally does,
however. At normal times the block gauge never goes above 160 or 170.
This time it was above 185 and appeared to be climbing. Someone said a
stuck thermostat could be the problem, and that seems to be a good
idea, but it doesn't explain why my 2nd radiator fan didn't come on.
What is the best way to check to see if a radiator fan is going to
turn on when it should? Do I just let the car sit in the driveway and
idle until the gauge gets really hot and if the fan hasn't turned on
then I know the little sensor isn't working? Or is there a more
effective way? Thank you for your help.

Chris,
Is your primary sender still located in the pressure tank?
You say the secondary sender is on the block and that gauge was reading
normal at all times. I would regard that one as Truth and the
fluctuating one as Rumor.
What's your water level like?
When I first got my Pantera I drove it down to Jack DeRyke's house. On
the way I noticed the temp gauge rising alarmingly, but then it came
down again. Then it went way down, and then the motor started rattling
and steam came out, so I pulled over on the freeway.
Mike DeRyke came ti the rescue with a 5-gallon can of water. We topped
it off, I drove a but further, topped it off again etc until I got to
their house.
A hose clamp had come loose and one of the radiator hoses under the car
had partially come off. It was a simple matter to put it back into
place and tighten it up and then refill the system. But it showed me
the value of having the e gone temperature measured on the engine, not
the bottle. As the fluid level dropped the car started overheating
which reflected on the gauge. As it further dropped, the tank became
empty and themselves started reading ambient air temperature which is
why the gauge fell. In the meantime the engine was cooking itself.
Lucky it started steaming and rattling before it just blew up entirely!
