Engine Replacing A Heater Core

Honestly I think it would've taken longer trying to dremel a hole out of the side of the box instead of removing 2 nuts

once you get in there its not that bad. just time consuming. give yourself a weekend to wrap it up and all will be good.

im going to try

i dont have the console to woory about.i guess thats a plus?i do have another car to drive if it takes more than the weekend but its not a Stang,lol

All I know is ive done it one time and it doesnt matter if it takes you 1.5 hrs or 2hrs or 24 hrs....after 15min...youll wanna blow your head off!!!

the job is a pain in the ass. i did not find it to be as dreadful as its made out to be though. it took me like 3 hours my first time. granted, i do know my way around most of the bolts pretty decent.

it can be done with normal hand tools, its straight forward. no reason to be afraid of it.

finished my heater core on 85stang.took about 8 hours,next time wont be so bad.
still it isnt fun

well done. told you not to be afraid of it.

Quick question for you all.
If a '87 didn't come with A/C, how had is it to convert the HVAC system to include A/C?

Thanks

heater core

Im removing my heater core as we speak. but I cant move the box out to get the back 2 screws. I losen the 2 nuts on the fire wall and the 3 bolts under the dash. removed the heater hose, and left the AC still on. I tryed pulling the heater box as much as i can but its no where near the much as i need to get to the rear screws. am i missing something?

I changed the heater core in my 87GT years ago, i remember wishing i would have taken a pic of all the stuff i had to remove to get at it. I changed it while parked on the street in from of my house and boy was that a mistake!
After all was said and done I couldn't believe how inexpensive the core was and how ridiculously expensive labor is...but at least i knew why in the case of the hidden heater core.
Has anyone ever tried to make a simpler way to the "hack job" method? I mean incorporating a clean cut out and rivet system to aid in future exchanges?
Usually I only change the core once if at all with each fox i get but it would still be good to know if i had to do it again on the same car it would be a 20 minute process instead of 2-3 hours.
Like some previous people stated it can be done in 1.5 hours once you get familiar with it!

Here's what my ALLDATA says:



Hope that helps.
