Just do a Search "heater Core Replace" and you will find threads and maybe the Stickies at the top of the coolant section will have info. I believe the Chilton Manual ($20 at most stores) also has this documented. Pretty straight forward project really with one "Bugger" of a screw to get to near the FW thats in a tough spot to reach. Removal of the Passenger Seat was a big help for me and only took a few minutes and well worth the extra space you get to work.
Once you get the Plastic cover off, you will notice a seal of some sort in the Channel that seals it to the bottom of the box. I just used RTV in the Channel and it appears the factory did this as well. Let it set up for a good while and then install.
