The reason for the grill block is that your cooling system is designed so your car can drive through the desert on the worst day of the year using A/C and still cool everything adequately. In winter, the cooling system is incredibly oversized for its application, and in summer its still quite oversized. Thus, in winter you can block off a ton of grill area and get away with it. In summer, you can also block off a fair amount.
