my 90 f150 300 I6 had the same problem. whenever i looked into it i found the thermostat was rusted completely shut, and my water pump went bad (since no water flow). seems the previous owner of my truck neglected to flush the radiator periodically. even though no water would flow through the motor, the thing ran alright air cooled(not recomended)

it wouldn't hurt to check it. the thermostat is behind the upper hose connection to the block. also check the color of your coolant. mine was brown which helped me find the rusty thermostat. whenever you get your themostat out put it in a pot of boiling water and see if it opens. if it does not then your problem is probalbly a blocked hose or fitting. although its alongshot, check the water pump too. if it siezed then you will get no water flow, and more expensive to fix than a thermostsat.
