This thermostat came out of my Euro Pantera's engine. I installed it along with a Flowkooler water pump a while. I am trying to determine its temp rating and cannot find a useful value in the stampings. The stampings are:
TOWARD ^ RADIATOR
21084 07
I searched the Internet for these stampings and could find anything useful. Does anyone have any insight on this?

Thermostats have a fairly good record of failure. While you are there, why worry about the old one that you apparently have no idea of its history or length of service. Just replace with a new one from Tim Meyer and move onto the next task

Today I just finished replacing the thermostat with a new 180 degree thermostat and restrictor plate from Tim Meyers. The above thermostat is only about one or two years old and I am curious about any forthcoming temperature changes in the car. When I installed it a year ago it was supposed to be 180 degrees but now I have some doubt.
Steve,
They are usually marked on the "pellet".

This one does not have a marking on the pellet.
Drop it in a pot of water and heat it up. See what it does, if anything, and at what temperature.
Great suggestion. I do not have a cooking thermometer and only have an infrared laser thermometer. Do you know if that will work?

for me this works.

Not too important. In my experience, what temp thermostat it is makes no difference in how hot the engine runs once fully warmed up. A 160- thermostat opens quicker but runs at the same temp as a 180 or the now-rare 192 after 15 minutes or so. I solved my special Cleveland thermostat problem decades ago by blocking the recirculation passage in the water pump and the brass washer under the T-stat and use a 351-W (or 302) thermostat. Works for me....
The new Track Boss thermostat from Tim Meyers is installed and working correctly. The car now holds a steady temperature. The thermostat that it replaced (top of this thread) fluctuated as much as 15 degree. I got it only a year ago and probably ended up with an imported knock off although I thought I was getting Robert Shaw or Flowkooler.
Good to hear. What rad cap are you running?
Stant 16 pound. The same one has been on there for a while, maybe two years.
10230 correct?
I was mistaken, the cap is from Napa.
