I was going to start a thread about this but will chime in here since I am having a similar issue. The difference being that I have not flushed my cooling system or made any modifications since I bought the car in December.

This infared photo was taken today after driving in rolling hills for about 20 minutes. Engine idling, 70°f outside. The coolest radiator temp is seen on the lower passenger side (appx 90°f). The warmest temp at the top is about 150°f, and appx 125° in the middle.

What surprises me is the temperature difference left to right. The radiator appears to be divided into 4 distinct quadrants temp wise. Does this look normal? Clogged tubes @ the bottom
