Question about 1984 Ford F 250
The procedure to replace heater core on ford f-250 is as follows:---
Disconnect battery ground cable.
Disconnect cable from temperature blend door and the mounting bracket from top of heater assembly.
Disconnect blower motor and resistor electrical connectors.
Disconnect and plug hoses from heater core.
Working under instrument panel,remove 3 nuts attaching left side of heater assembly and right side of plenum to dash. remove 2 screws attaching right side of heater assembly to dash, then lift heater assembly out of vehicle.
Remove heater housing plate attaching screws, nut and bolt and the plate. slide heater core and seal out of heater assembly.
The hardest part is getting to the heater hose connections to the heater core. You have to dig around behind the A/C lines and it is under the cowl under the hood. The fittings are snap type.
