I would start with checking your thermostat and thermostat housing. See if its regulating. If it is not replace the thermostat.
The thermostat is in a housing at the engine end of the upper rad hose. When you replace it make sure the spring goes toward theengine.
Once the thermostat has opened, the hot coolant flows from the thermostat housing on the engine into the top of radiator and out the bottom of the radiator back into the water pump.
To change the thermostat on a 1973 Ford Mustang with a 302 engine, drain the radiator. Locate the thermostat under the upper hose assembly and remove the required bolts. Place the new part in position and replace the hose assembly before filling the radiator.
