I have a grill block, but my engine was still running 130-140*F on the highway this winter. So I added a radiator block, too. I made mine in two pieces, overlapping like sliding closet doors. I can adjust the opening by sliding one of the pieces to the side. I've learned how much opening I need for various temperatures, and I'm keeping the engine at 180* on the highway (200* on side streets) now. Radiator block been velly velly good to me.
