Yes, what Avi says and also:

Make sure the fan runs...
if the radiator is cooler at the bottom check the thermostat... check it
anyway, pull it , boil it in a pan of water with a candy thermometer, make
sure it opens at the proper temperature.

If your radiator has had a lot of stop leak added you may find the flow has
been stopped too. My son's white '84 4kq had a  radiator in which some one
had apparently added water glass to stop a leak. They effectively stopped
the flow of water through the core ... permanently  :-(
