whats the rule of thumb?
if i had more material left over from the Caliber's undertray, i would have filled up the whole grille without the gaps on the sides

The opening(s) for the grille block will yield the most cooling per square inch if they are directly in front of the radiator fan. Better to block the sides, and open the center.
How much over 200* F? Does the fan cycle on an off in slow moving traffic or just run constantly? I'd want the former or be d**m sure my temperature gauge read accurately and never climbed over 202* F??? (No good source/reason for choosing that number. But there would be a number and it sure would be well under 210* F.)
If you go to
History : Weather Underground, you can page through charts of the high/low temperature for you're area during the last year - like this -
and thus make an educated guess if size of the current opening will be a reasonable compromise for the next couple of months.
