Diesel_Dave points out that the grille block has become a problem, not a solution, if coolant temps rise above thermostat opening because of it.
I work a 6/2 week. The short runs to/from work weren't a problem, bu the days off with errands to run finally got me to remove the lower of four portions of the GB once we became full-time in A/C season (May 1 last yer, June 1 this year).
Over-inflation of tires and blcoking heat exchangers can have some serious consequnces (braking for one, engine longevity on the other).
