Check coolant level, is temp at running temp aprox 180 - 200deg. Water pump would be last option.

When engine is cold, and if you have a expansion tank system, check water at radiator cap. My guess is low coolant too. Could be if you have a bad cap or something is loose on line to expansion tank, coolant will not return to radiator. Also look for a small leak if radiator level is down.
