Thermostat opens at 83 degrees so engine should settle at about that temp in normal driving. My XSi (similar engine) also displays a cool temp (about 75 degrees) in normal driving. Have changed the thermostat in case it had stuck fully open n still the same. Concluded that the blue temp sensor (which feeds the gauge on the dash console) wasn't reading accurately.
Other possibility for running slightly on the cool side is a rich fuel mixture. Don't think that would explain 13 degrees below normal tho.
