First, be sure to check your coolant level when the vehicle is cold. Top it off if required.
A bad water pump will often leak from the weep hole towards the bottom of the pump body. Crawl under your truck and take a look. Any leak will be obvious. If it is leaking, you have to replace the pump.
If the weep hole is dry, your thermostat is most likely the culprit. 5 bucks for a new thermostat and gasket and 15 minutes of labor and you'll be back on the road.
When thermostats start to go bad, they often stick in the closed position. If the thermostat doesn't open, the hot coolant from the engine block can't flow to the radiator to be cooled, causing the engine to run hot. A new thermostat will most likely fix the problem.
