When you say it runs hot, at what temperature is it running at? Are you seeing the temperature on the gauge or did you measure the actual temperature at the thermostat?
check aroud your top radiator hose, see if there is a bleeder valve for bleeding outair in your cooling system, if air is traped in system the engine will over heat
