There are several proceudures. 1. Warm up eng. remove fan belts, remove rad cap. Examine for bubblesf bubbles, your head gasket is leaking. 2. Slipping water pump impeller. Remove lower radiator hose & belts. insert coat hanger wire while turning pump 3. Upside down thermostat, defective thermostat. 4. If you already took out thermostat & it over heats, it is almost certain a bad head gasket.

A WAY TO CHECK FOR A PLUGGED RADIATOR IS WITH ENGINE WARM AND NOT RUNNING, RUN PALM OF YOUR HAND OVER THE CORE OF RAD IF THERE ARE COOL OR COLD SPOTS THE RAD IS STARTING TO PLUG OR IS PLUGGED ,AT THE SAME TIME CHECK FOR LOOSE OR ROTTED FINS , HAVE TO BE TIGHT TO TRANSFER HEAT.

Has the radiator been to the shop and cleaned? A reputable shop will pull the tanks, rod the cores and put it back together for @ 100 bucks. A honest shop will also let you know if there is not enough cooling capacity. A 3 core may not be enough.
