Which one of these switches would be better using a 195* thermostat?
'87 Grand National
1 terminal, 3/8-18 npt, 210 ON-205 OFF
'90 Ford Escort.
2 terminal, 1/2-14 npt, 212 ON-192 OFF

With the escort one wouldnt the fans come on, and then not go off until the thermostat closes? I was thinking the grand national switch would be better because it wouldnt always be opening and closing the thermostat, but is 210 to hot?

I don't follow your reasoning: if 210 is too hot, isn't 212 also too hot?

If you are concerned about the thermostat opening and closing, then just get one that is a few degrees lower than 192 degrees. Once the themostat is open, the fans and the switch will determine the temp. IOW if the thermostat is 185, for the most part the engine will be running between 212 and 192 if you use the escort setup.
