What should be my temp?

If a thermostat has too high of opening temperature the coolant can circulate too fast not being allowed to cool in the radiator. The thermostat is constantly opening and closing regulating the temperature of the coolant. Therefore if you have a 195' thermostat the temperature will probably not get below that temperature. Like wise if the rating is too high the coolant will have to get to that temperature before it opens allowing flow to the radiator.
I had an engine once that constantly heated from the time it was new. Went to replace the thermostat and found it had none from the factory. Installed the correct thermostat and it never heated again.
