What some one with an upper grill blocker and a scanguage could do is select engine/coolent temp on one of the displayed guages and do an EOC and see what the guage reports. I suspect that there would be little if any change in engine temp. all engines heat socke when the car is stoped/parked and turned off which would be no different than turning off the engine when coasting. Although when coasting there is some cooling due to forward motion through the air...
