Pshaw. The temps aren't that much higher. Insulation as it is on my stuff mainly serves to prolong cool-downs thus reduce cold starts while not increasing running temps- according to coolant gauge- all good stuff.

Pshaw indeed. I saw that and rolled my eyes. Yeah, hotter, maybe...and if the grille block is done wrongly the engine will overheat. But overheating an engine isn't the same as holding a blowtorch on a piece of metal until its crystalline structure starts to change.
