No the AC system is unaffected, its part of the cooling system. Hardest part is getting all that crap back in there

Agent 86 has posted photos of the box that I found very useful in locating the upper left screw. That and taking out the seat are key elements for me. Also measure the amount that the rod protrudes at the adjustable door before removing it.

Shortly after I got my "new" '88 IROC-Z a copla years ago I did the heater core; with the FSM, patience and a copla days it was no big deal...

I'm just being paranoid, tomarrow i'm gonna bypass the core w/ a L adapter so i can drive it without the windshield fogging up. decided that before i pull everything apart i'll order the core and a new blower motor

When you do get that new core, do a pressure test on it before you put it in the car.

I did a h/c on another vehicle, installed the new one, buttoned up the job and did the road test.

Yep, the new h/c leaked!
