The thermostats in the newer cars are 195.  Operating max temp is set by 
the fan turn on temp in the ECM/PCM.  thermostat just sets minimum 
operating temp.  220-230 is not for emissions, but efficiency and 
economy.  Change the fan on/off temps and the Mileage will decrease 
slightly (a couple percent).
