I am replacing my heater core on a 1992 bird, I followed a couple posts and removed my passenger seat for extra room to work on it. I am following the chilton book , it shows to pull off the shroud covering the core. I was able to to get out 3 of the 4 screws.


How do you get that damn fourth one upper left side? I tried to reach in with a 6" extension but there is so much wiring in the way. Chilton doesn't call for the removal of the dash or anything do I need to remove the dash to get to that last screw? Or is that screw just a pita to do. Maybe I should borrow my kid's hand ,and have him stick it up that narrow area .

This might help a bit...

I don't know if this pic will be helpful or not. I do know, however, that in my particular case, the upper bolt wasn't really a problem. Without removing anything other than the lower panel, I was able to access all that I needed.

my heater core leaked out, I bypassed it and so now its just in the dash not connected to anything. Can I remove it, and still drive around? will it effect anything to not have it inside my dash?

 

no i dont think it will hurt anything, but i would cover up the two holes left when its gone in the firewall to keep things out of ur dash area.

 

mine was a pita to get to I finally gave up and removed the eitire dash once that thing was out of the was it was alot easier to work on. Course putting it back in was a learning experience

 

..

 

where is that guide? is it for camaro or bird. can you take that piece off on a camaro?

 

that top screw is a pain in the *** my little tip is once u get it out dont put it back lol i used a rachet with a flex neck on it and it took like 20 mins to finally getting it after taking dash pad off and all to find it it took awile to find i ended up lookin inside the box while on the car to find it.

 

Yeah I had a similar problem with mine on that top screw. I finally gave up after about a 1/2 hour of trying and ripped the cover off breaking it around that screw hole (and I don't regret doing it). Course all I had was regular rachet and socket sets nothing fancy.

 

ya ive been telling myself that when i get to it i wanna just bust off around that screw hole instead of the whole dash tear down. does that make a bass rattle? we all know you havef a wicked system :hail: :hail: :hail: :hail:

I got to the top screw by pulling the dash out about 2 inches. Removing the dash pad and the passenger speaker. That gave me just enough room to get to the top screw with a 1/4 drive ratchet, an extension and an flex socket. Still was a pain though. But it worked.

 

On the birds its a piece of cake, you just remove the hush panel and the trim piece with the performance suspension badge, and GM left a nice access hole thru the dash. Some long extensions and its a breeze.

But in all fairness the one that I replaced had been done incorrectly before so I got to remove about 90% of the dash so I could replace half the heater box.

 

How do you bypass the heater box? o you do it at the heater control valve?

 

you take the 2 hoses that goto the heater core in the firewall and put a fitting from them so they just go together instead of into the heater box... want pics? I did it but im thinkin its leaking because I checked my overflow tank and its EMPTY

 

Yes...pics would be cool. Thanks
