Temp looks ok....I guess....numbers look funny LOL
Mine runs about in the same area.
FLUSH THE CORE!!!!
mine done the same and when I flushed it out I seen some crud but didnt think it was much,and noticed no differents in flo.the next drive....DAMN....had to roll down a window.
unhook both heater hose and flush it back and forth several times.
if your system is real dirty i would add a cleaning flush,flush the system and then do the core again seperate.
