It sounds like you have a 195 degree thermostat installed, which is what Ma Mopar recommends our engines have (and what a parts store will give you as a stock replacement thermostat), and running at 195 to 200 degrees would be normal for a 195 degree thermostat, as long as the temp is basically staying steady at 195 to 200.

The things you want to watch out for are:

A stady increase in temp when running down the highway. This would indicate that your cooling system is undersized or plugged up - you're not getting enough coolant flow.

Or

A steady increase in temp when idleing or crusing slowly. This would indicate that there's not enough air blowing through the radiator.
