What coolant temp does a 4.8/5.3 go into closed loop mode? My swap is running about 180-195, is this high enough for it to stay in closed loop mode? It runs great, but I was just curious about the open/closed loop temp.

Thanks,

on most 98 to 02 ls1 or trucks 5.3 or 5.7 liter they go closed loop at 92 degrees but I would think yours goes closed loop way before 186
