W-126 Overheating problem

I have a 1990 300SE with about 190,000 miles. I replaced both aux. cooling fans this past year, the engine fan clutch, thermostat, water pump about 40,000 miles ago and I replaced the radiator about 2 years or 55,000 miles ago with an aftermarket radiator made in Israel. The car is experiencing high running temps at 65mph+ with outside temps above 78F. It will go right below the 100C mark. In stop and go it will raise to about 110C and with the AC on it will go to about 115C before I turn the heat on to cool it down. I think the aftermarket radiator is the cause of my cooling problem. Is there anything I can do to check it? What are your thoughts?
