I had a plugged radiator causing overheating. I could tell because there were "cool" areas on the radiator that you could feel because there was no coolant running through that part if the radiator. If you can get your hands on it while it is running (difficult & dangerous) you can feel the cooler areas. The temp should be homogeneous across all areas. Also when measuring the air temp coming over the fan, there were cool zones. I used a long temp probe and positioned it between the fan and radiator surface. I had to loosen the fan shroud to get it in there.

If it old just replace it.
