Chris,

You already know what kind of thermostat you need to replace it:

<https://www.summitracing.com/parts/bra-333-180>
summitracing.com<https://www.summitracing.com/parts/bra-333-180>
[X]<https://www.summitracing.com/parts/bra-333-180>


You will also need a new water neck gasket and these are vastly superior to paper gaskets:

summitracing.com<https://www.summitracing.com/parts/fel-35041t>
[X]<https://www.summitracing.com/parts/fel-35041t>


Order both of these now so you are ready to fix your car when the PNW guys come over, not just take it apart….

Mike

  I just hate having to keep asking for help from everyone all the time.

  Thank you!

  What is your thermostat rating? If the thermostat is 185F, it sounds
  like the gauge in the block is reading the correct temperature, then
  once the thermostat opens it allows a rush of cooler coolant and the
  gauges typically drop. If the second fan thermostatic switch is 185F as
  original the second fan might not come on as the coolant in the
  radiator is being cooled and slightly colder.

  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.

    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!

  Hi folks, a funny thing happened on the way to the Rotary

    My
car's heat gauge began to show hotter and hotter and was in the
  red
pretty deep. The secondary gauge I have installed which comes from
    the
block showed the temperature getting to about 185 or so. My first
    fan
kicked on, but the 2nd fan never did.  Normally it comes on
  shortly
after the first one.  I don't know if the gages were reading
incorrectly or what, but it seemed as though the gauges were
    continuing
to climb.

On my way home the same thing happened until about half way home
    when
all of a sudden both gauges dropped down to their normal range.
  Any
ideas?

Thanks.

Sincerely,

Chris
