not difficult, but just a lot of annoyin' work to be done. you have a bunch of shiet to remove just to get to that dang heater core.
- disconnect battery, and remove (if you have AC)
- drain coolant
- disconnect outlet heater hose and valve heater hose and cable-to-valve
- remove 1 nut on firewall, on engine bay side
- safely release refrigerant (if you have AC)
- remove a bunch of junk just to remove dashboard (ie: hazard light and other switches/buttons, radio, climate control and cables, lower-dash center console, glove box, passenger side SRS if you have it, wirings)
- remove steering column brace and lower steering column
- if you have AC, disconnect high and low pressure lines on firewall from engine bay-side. remove AC box. otherwise, remove vent chamber between blower and heater box, if you don't have AC
- remove curved piping on passenger side
- remove heater core box. be sure to tilt the spouts upwards (so you don't drip any over into your car)
- finally you can remove your dang heater core
this would be a good time to vacuum, wipe down, and just clean all that dust and, possibly, coolant spots/leaks. also, be sure to orgaranize all your screws into sandwich bags and mark down where they all go. or you're screwed.

ps: one more thing. don't buy an aftermarket heater core from AutoZone. it doesn't fit. their math was way off.

If you need one, I'm selling the whole thing.....$25 plus shipping.
Came out of my 92 hatch being stripped for parts. I sold the dash and needed everything out of the way to remove the wiring harness.
