Only way to remove the heater core is full dash removal and heater box removal, means A/C degas as well.
Other choice however is remove glove box and CUT the back of the heater box and pull it out that way, looks possible, I have a spare heater box at home, I will try take some pics so you can see where things are located if you want to attempt this option.
I have pulled my dash at least 5 times, its not really all that hard :0)
I did put something here, but it vanshied, I think
Yeah, dash out. Had to change mine two days after completing the el dash conversion (bloody heater fan didnt work). It is possible to do without pulling the dash right out, but all the bolts need to be undone, and the center console out. Also, the EL heater box is exactly the same. Im using one in my NA, bolts straight in.
Ah that's crap eh, I just sold an EA Ghia heater box yesterday lol.
I'm pretty sure you don't have to take the whole dash out if you're replacing the core, you may only need to remove the glove box and panel behind it, along with the whole stereo bit. That should give you good enough access, someone told me they did it that way a while ago.
Yep you have to move the dash back but like one of the replies above you don't have to take the dash right outof the car you can just have it sit on the passenger seat and pull the heater case from the passenger side out.Remember to remove the foot duct as its easeir and when you drop the column undo the foot plat as if this is not done you can pop the bearing out of the sleeve or make the bearing noisy and that means a new column.When moving the heater case out lift it has high as possible as you could also break the actuator at the bottom of the case.
The EA to EL heater core is the same,I think even AU.The fans are the same as well right down to the connector.
Won't be to hard just seal it with windscreen sealer or something that has a bit of give other wise the sealers that go hard will allow condensation to come between the split inthe case and thus onthe floor again.
