Testing new thermostat
Bought a new Robertshaw thermostat BRA-330-180 for my 66 GTO engine rebuild. Decided to test it before installing it. Suspended it in a pan of water and made sure it was not touching the pan anywhere. Watched the meat thermometer climb up to 160, then 170,then 180, but never saw anything on the thermostat move. Temp kept climbing to 210, but still no movement on thermostat. I’ve never done this test, so wasn’t really sure what to look for. I was looking down at side B as the temp climbed. Side A was facing the bottom of the pan so I could not see what was happening with it. Is this thermostat a dud, or is this a case of operator error? What should I be looking for to confirm it is opening at 180 degrees
