easy remove the heater hoses from the engine bay side of the heater core. remove the glove box, remove the black cover over the heater core under the dash. i think there is like 2 screws that hold the heater core in the car. remove them and wiggle that sob out. reinstall the same way.

I just completed the swap. It was pretty easy. heres what I did:
1. disconnect the battery
2. Remove the heater core hoses & remove the 6mm bolt & clamp that hold the hoses in place.
3.Open glove compartment, squeeze the sides together to disenguage the tabs that hold it in place.
4. remove the 3- 6mm screws that hold the glove compartment door on.
5. remove the heater core cover. This is a black, plastic cover that sorted has a elbow shape to it.
6. remove the heater core clamp which is one 6mm screw and pull heater core out.

bingo bango

This was alot easier than I thought it would be. Removing the old heater core and installing the new heater core took me about 1 -1.5 hours.
Basically what "Jsteele90" said
