I should take an experience person 7.0 hrs to complete a heater core replacement.
It maybe a good idea to replace the blend door while you in there. If you having trouble with heating and cooling coming out the vents try looking up "heater treater". They provide service kits that take much less time to repair broken doors inside the air condition box.
On the F150 and Explorers I''ve dropped the steering column on the driver seat and removed the dash. I take more time fighting the air condition box with the dash in your way and it makes it a much cleaner repair to do (heater core remove and replace).
The blend doors in the air condition box are a common failure for breaking.
If you have any more questions feel free to reply.
