Hi guys just sharing here..   (dont do what i did)

 

Well when i got the car (96 legacy wagon), i found that the heater core was bad,,  i bypassed it but winter was coming so i tore it open and changed it out.  i follwed this:    http://beergarage.com/subyheatercore.aspx

 

Well when i finally got the heater box out,, i couldnt get it apart,,, i took out what i thought were all the screws,, but didnt take the one out in the bottom center..    

I thought the big pin that was going thru the flapp door was holding it together,, so i hit it with a hammer to drive it out/ down thru....  (wrong answer)

I didnt know it was all one piece plastic.  duh... So i finally got it apart and found that i had broke the bottom of the door flap    at the bottom as you can see in picture 2.

SOOOO  i glued it.. Yes,, i used some kind of super epoxy from advance auto...  it seemed to be ok. 

 

Put it allll back together,,, i had heat!  I had air.!!  

 

Now its november and i dont have any heat.  AT ALL.    

 

Soo im going to tear it all down again and go back in.    So this is a PSA, dont hit that plastic thing with a hammer...   and 2  dont use glue.

 

Is your baffle door opening? If the coolant level is correct(check it) it is not the core that's the problem. Make sure all your fuses are good.

 

O.

well It was the baffle door which I broke in the middle of the heater core replacement.   I believe its broke again,, and not opening.  I will check the fluid again to make sure also.

Its a bunch of work, but your best bet is to hit the yard and grab a good box.  Replace the entire thing.

yea hammer=leak replace! use subaru coolant conditioner or another stop leak product just in case! 

I checked coolant,, cant fit any more in there.    The Flap door HAS GOT TO BE closed. Started tearing it up...  procrastinating,, lol,,,,,,,,,,,,,,,,,

Yep, gotta be careful with those blend doors.

 

You made sure the cable was attached at both ends first?

Double post...
