Don`t forget to pull a vacuum on the system to get rid of the trapped air, or you could have overheating problems.
Shutter will open up if engine gets got. I do not know what that temp is, but since the fans don't turn on until 224 Is imagine the shutters are about the same temp range.
Check High Horse Performance (HHP) sells Hemi t-stats 180° and others. Mishimoto and one or two others if I remember correct. If you get a tune/tuner, they'll advise you what to set the Fan temps to also.
You are spot on here. I flushed a gallon and a half of coolant out of the radiator (about half of the system) and refilled with the peak. Did the old school method of burping (with my custom funnel!) heat on, got up to temp, revved, opened and closed tstat multiple times, restarted multiple times, capped it, drove it, opened in burped it again. I think there is still air in there as it heats up pretty quick at idle. Fine while driving but im going to flush another gallon of coolant and then refill using this that should be arriving tomorrow:
