You going to tell us about the "issues" or should we just guess?

I have no heat, everything seems to be working correctly but it blows cool air doesn't get hot. I replaced the thermostat and the heater core I filled it up with coolant ran it for an hour and still blows just cool air. I did work all the air out of the coolant system.

You seem to misunderstand (or, at a minimum, have failed to report) the fundamental fact that HOT COOLANT MUST FLOW THROUGH THE CORE(S).

Until you have verified that, you're wasting your time by not properly diagnosing the fault.

Intermittent heat

Expedition 2003 5.4 with intermittent heat. Have replaced thermostat, heater control vlv, checked hoses and inspected wtr pump ? When not blowing hot it will sometimes overheat, bowling over from reservoir. At these times the hoses are cold as well ?

Any suggestions
