You might try ducting too. Yesterday night, just before sundown, I took 45mins and installed ducting behind my 80% lower grille block in order to deliver as much available air as possible to the radiator. The engine SEEMS to be a few degrees cooler. The real test will be if the coolant temp stays under 206, which seems to be the moment the fan cuts on. A second benefit is that my WAI gets warmer air sooner. I'll have to watch that too, as the air intake temp hit 45-50 degrees above ambient temps quickly.
