How to service the heater core on Ford F-250 Super Duty?

The service of the heater core begins with clamping off all water hoses followed by disconnecting them and removing the clamps. The closet door should be lowered after both stops have been released. The procedure to take out the panel/floor door vacuum control motor requires disconnecting the vacuum line and unscrewing the motor prior to rotating it so the lever disengages. Handle the fragile panel/floor door lever with extreme caution. The electronic blend door actuator assembly can be removed when the electrical connector is disconnected together with its two screws. Unfasten the seven screws then disconnect the wiring harness retainer from the heater core cover by keeping the cover in a vertical position to safeguard the heater core housing. During heater core replacement, manually place the blend door into correct position so the electric methods stay off to minimize potential damage. A gasket must be placed between the housing and cover before reinstalling them. Reinstallation follows the removal steps and ends with filling the engine cooling system.
