Man, what a pain! Finally did it though. Got the new center console done too and carpet is coming along. The car finally has a VIN on it again after 15 years!

Gawd, I hate that job. Kinda cool doing it with the engine out, though....
Nov 02, 2009 06:39:18
Even easier with both the engine AND the dash out! Smart move, Paul, lookin' good!

Good job. It's so rewarding to see a painted heater box sitting in a clean engine bay after all the struggle. For those who have yet to put one back in, take a look at your rubber heater outlet seal. My new one plus the box added up to 1/4" too big for the hole. Since I had no confidence I could compress the seal that much without doing other damage, I sliced a bit of rubber off, then lubed it with vaseline and it popped right in. There was still enough rubber to require a solid thump to get it in.

What an inspirational picture for me! Since I have the dash and all the other heater parts out, I'm going for the heater! Keep the pictures coming, I appreciate the detail.

Isn't that installed backwards? Just kidding, I've done this and couldn't believe what a pain it could be. I had to make up my own seals as the ones provided would never have compressed enough to fit. Ray

Seal? There's a seal? Uh oh. I just used foam tape arount the perimeter of the hole. Will this suffice? I am NOT taking it back out so it'll hafta...

Mark,
Sounds like you've already done most of the work. The box itself comes out easily. Just release the control cable (at the knob, or at the box, accessible through the air vent in the passenger footwell), remove the screws that hold it down and you're there. Have a radiator shop boil out the heat exchanger. The box is pretty straightforward. Clean, paint, replace the foam that is inside (not sure what that does; maybe reduce air turbulance from the fan?) & put it back together. Pic is before....

Paul,
The earlier cars don't have the seal (really a rubber block). I don't remember when the change was. The block mostly serves to locate and hold the two flex hoses that direct the air to the footwells/defrost routes. ( I believe the older cars had a couple rigid tubes instead.

WHEW! Yes, that is how it is. Just two plastic tubes to connect to the defrosters. I should be ok.

I like the dash wiring picture, a bit more original than the mess behind my dash!

I retro fitted the 1971 B to the defroster tube method. There is much more air flow to the defrosters. Coupled with an uprated heater core there is lots of heat to the windshield. Next thing is get more air moving over that core.
Guess it is easier with less hair to get into that little footwell to hook up the flap control cable :D

I've not done this job myself yet but I got a tip from a guy at a show,Just like you steve he used vasaline but first he heated the rubber up with a hairdryer to make it more supple,might be worth a shot next time.
