195 would be correct. If the engine runs too cool it may run rich as the ECU will think the engine is not warmed up.

In addition you'll get a check engine light with the trouble code for the engine being below operating temperature. On a cold start up the engine must reach operating temperature (195°F) within 9 minutes. Otherwise the code will set. HTH. -Jim

I monitor the coolant temp while driving using a OBD 2 and unless i stop the range is about 150-165, when i sit at idle for like 10 mins it goes up over 200, do you think its cuz the thermostat is junk ?
