I was experiencing high coolant temperatures in Winter 2011-2012 with a full grill block. If I P&Ged (engine on), coolant temperatures stayed about 186ºF during highway trips. When I had to run the engine steadily, temperatures climbed to 204ºF. I later found I had a pinhole leak in a radiator hose, but the point was made. My engine ran cooler with engine on P&G than it did cruising at roughly the same steady speed.
