Well first of all it's warm down here so keeping the engine warm is not a concern. Last year I did tape up both grilles and monitored the coolant temp. Normally it stabilizes at 185F. With the bottom grill blocked, the coolant temp did not change. With both blocked, the temp would cycle between 205 and 195 because of the fan kicking in. So one or the other is fine, but both is not good.

From an aerodynamic perspective, grille blocking is worth looking into. In fact, I will be heading up north next weekend to do some "research".
I also have one more aero mod in mind. Hopefully in a few weeks I will have something to show.
