The Heater core is difficult to replace on the F150 since it is buried in the plenum box. Getting to the core involves removing the steering wheel, steering column, complete dash panel, evacuating the AC, draining the radiator, and finally removing the heater box. Once you have the box out(8-12hrs), the core is simple to replace.
You want to be sure that the core is the problem before you undertake this process. If there is a strong smell of antifreeze in the cab or a puddle of coolant on the floor, the diagnosis is easy.
Check that the radiator is full, not the overflow tank, the radiator. On a cold engine you can remove the radiator cap and check the level. It should be full. If there is air in the system it will affect cab heating and engine cooling.
Another good check is to feel the two heater hoses going into the firewall from a cold start. The hoses should warm up at about the same rate and get uncomfortably hot-close to radiator temperature.
If the core appears to be OK, the next concern is with the blend door that diverts air through the heater core. This is a common failure on the F150. We have a video posted on our web site that shows how to diagnose and repair the system. Please follow my user name back to my bio page to find a cut-and-paste link to the web site.

How does the heater control valve for f150 operate?
There really isn't a heater control valve. The coolant flows through the heater core at max pressure and temperature is controlled by controlling the amount of air flowing through the heater core. This is the function of the blend door and this is a fairly common failure on Ford trucks. Check heatertreater.net for diagnostic information and suggestions on how to repair the system.

Can you find the heater vavle in a 2000 Ford F150?
There are two "valves". The heater control valve (YC3Z-18495-BA) located by outside of the body near where the running board would mount. In terms of front or back, it is closer to the trans. It is connected to the top of one canister that is connected by a long hose that goes to another canister located on the other side of the truck's frame. There is also a valve (YL7Z-19D963-BA) located in the climate unit behind and under the passenger side of the dashboard.
