Get yourself a Chiltons repair manual, do hours of searching on the internet, and if they make them try and find a Factory assembly manual. Be prepared to remove the passanger fender to get to some screws that are inaccessable. It's a strait foward job once you figure out how to get the heater box/ac box and the ducting off.

That's about the easiest heater core replacement there is. The blower box does not need to be removed from the car. It's a 30 minute job if you've done it before.
Read a manual first.
Remove heater hoses.
Remove the panel from under the dash on the passenger side..
There's another panel closer to the passenger's knees that needs to come out. You'll probably need to pull the radio/ac cover plate to get to the screws.
Using the longest 1/4" extension you can get (like 3 feet long) and a 9/32" socket, remove the screws from the cover on the blower box. Feed the socket completely through the dashboard from a hole under that cover you removed to get to the upper screws.
Remove the cover and pull the heater core out. It's a tight squeeze to get close enough to see what you're doing. Take your time.
There are some plastic and foam pieces that must be swapped to the new one before reassembly.
