Hey with winter already where you are at, have you seen the trick for warming up faster in winter? If not, take the copper pipe wrap(to help prevent freezing) at home depot or lowes for 1/2" pipe and cut to fit in the lower front grill, I tie wrap them on. I have done this for the last 2 winter with no problems or over heating on warm days. It helps warm up the radiator considerably quicker on cold days to help blow warm air. But I love the heated seats and the electric heater in the vent to help warm the windshield on those cold days.
I may need to explain more, by using the wrap, over the cross bars, it will close off the space between the fins, thus it will close off the cold air going over the radiator, keep it cool longer on cold days.
