Grill inserts and Over heating

Over the past week I've noticed a lot a GA owners having overheating issues. If you have mesh grill inserts this may cause the engine to run a little hot. If you dont have inserts another thing that I've seen this summer is Bugs in the AC radiator. This blocks air flow Dramaticly from the engine radiator and the AC causeing them not work properly.
I have grill inserts and my temp, over all, runs about 5 degrees hotter. Even with a clean radiator. Just thought I'd share this tid bit of information. It may not be the cure for all overheating and AC issues but it's something easily fixed and probley the most over looked. Just clean them with a power wash at the carwash or a garden hose will work too.
