No coolant flowing

i started my truck yesterday it was pretty cold out went about 10 miles down the highway and the coolant started to get warmer then usual, and the heat was ice cold. I pulled off looked under the hood and there was steam coming the top of the radiator i was low on coolant and the lower hose was cold. I think it could be the thermostat is stuck. Any other ideas has this happened to anyone? thanks

Not up on 6.4's but the Ford thermostat usually fails open, other brands could fail closed. If the 6.4 water pump is like the 6.0 which is a plastic composite it could be cracked or missing some fins. Next thought is bad head gasket.
