Depends what degree of thermastat is installed, most popular are 160 or 180 degrees, the car will fluciate some depending on what kind of driving, if you are going up a steep hill the engine works harder and the temp will go up a little, compared to driving on flat road, the outside temp will also influnce the running temp.
