Replacing the heater core

[Impact Black]

Ok, I've browsed the fsm ON THE HEATING AND COOLING section, however I can't find the instructions for replacing the heater core.

I've already removed my dash and I can see the box that the core sits in, however I'm not sure how to open it and correctly replace the unit.
I don't want to damage it,so if anyone has the actual information on removing it, it would be great help.

you'll be able to open the box up. And you can remove the actual heater core itself from the box.

The box has to come out first, then you'll see a plastic keeper with a screw that holds the core in place.

ok, I'll look at pulling it out tomorrow. Just didn't see a write up in the FSM about it, so I was wondering
