So the previous owner of my tbird had a tune done on the car. The fan (03 cobra rad. & fan) kicks on at 191* according to the W&S infocenter. Was doing some maintenance and noticed the car has a 170* thermostat. Is this appropriate for the tune? Never had a problem with the car heating up or anything, but the climate here is pretty mild. What would be the appropriate thermostat for the car?
