REPLACEMENT OF HEATER CORE ON

1998 Ford Expedition • V8 2WD Automatic •

My husband and I are trying to replace the heater core on my 1998 ford expedition. In the manual it has a picture of the whole dash taken apart. Could you please tell me if we have to take the whole dash apart or if there is another way to take the heater core out and put in the new one. I hope so becaus e it seems really hard if we have to go through all of that
