Is there a way to remove the heater core on an 85 FB without removing the dash?

I doubt it. The box is tucked up there pretty good.

i pulled mine out without removing the dash. just make sure you get all the bolts holding it..and the coolant lines...

It's possible, at least on a 83. On my 83 removing the stereo surround and glove box gave me enough room to take it out, granted its a royal pain, but it can be done. Not sure about S3 though, that dash looks quite a bit more complicated.

mine is an 85. if i could have pulled my dash to get to it..i would have. but i didnt have to to remove the heater core. so it CAN be done.

I'd think you'd have to be Stretch Armstrong to be able to do it.

I did it

once without removing the dash and less than a week ago by removing the dash.

You'll have to remove the carpet panels on both sides of the center console, your radio will come out. the passenger covers should come out, along with the glovebox.

Once down there it's easiest to remove the motor, and the middle box thing and finally the heater core. Cause they are LEGO'd together.

The heater core it's self is held on with 3 nuts. and one metal cable on the drives side for the control.

2 nuts on top, and the tricky one is hidden behind the middle box against the fire wall holding the brass lines centered in the firewall holes.

Thats it

removal takes awhile cause of everything being kluttered. But the more **** you get out of your way the easier the job gets.

Give it a shot.

(P.S) the ducts are held in place with a plastic tab that you must pull out.

and the top to nuts are behind the center dash vents way up at the top.

There is nothing holding the bottom.

Now that you know all this it should be quite easy

also glove box removal


-remove the inside lock hinge
-unclip the light inside
-remove the side dash cover and the cover under the glove box to expose the last 4 screws that hold the glove box in place.

Thats it, now you know everything

Thanks Jimmy!

The A/C still works without the heater core right?

82transam

iTrader: (18)

no, not on a 83 anyway, all the ducting goes to the heater box. Oh and Jimmy, the middle box is the A/C evaporator.

Okay...

So the A/C Needs the heater core to work?
If so, then I guess it stays..

Well you can remove the core and put the box back in place. A lot of work for little gain though. Then youll have all you vent/def/ flapper doors and control availible.

Felix Wankel

you can take the core out of the plastic box, clip it back together and then seal the leftover holes up with some tape.

Don't take your heater core out! Whatcha gonna do when it gets below 85 in My-Mammy? Yule FREEZE!

i have no interior..so the heat radiates from the engine bay plus it comes through those neat holes the A/C and heater left...

Yea you could take the heater core out of the box and block the holes, but like was said earlier its not worth it. I'm removing the A/C in a similar fashion on my project GS, but then again the entire interior is coming out of that car to do a proper color change, so its really no big deal.
