Thanks for taking the time to do this again Brian.Sorry guys. I guess the host that the pictures were on changed something. I uploaded them all to Mud this time.... left out the last few that had more to do with the CB. Have a ton more pictures in that folder if anyone is looking for something specific let me know. I did this in 2008 and that was a sh1t ton of beers ago... I barely remember the details. I do remember it wasn't as bad as I thought it would be. The FSM was my best friend.
Later,
Brian
On my '94, the heater core had a "flared fitting" sort of deal (on the driver side of the heater core) that was sealed with an o-ring and held together with a copper clip. Basically, you slide the core and the short pipe together, and the o-ring gets trapped between the two matching flares that face each other. The copper clip is s spring clip that then squeezes the lips of the two flared portions together.
If you buy the "complete" heater core, you get those parts. If you buy the "bare" heater core, you don't. I agonized over that o-ring for days; ended up replacing it with another o-ring that was a very close fit. That, a mere soupçon of silicon grease and a reused copper clip. Of course, that joint is in the passenger compartment, way inside the dash.
Don't stress the clip, be careful with the o-ring and be *really* careful with the short copper pipe that comes from the heater core and goes through the firewall.
By the way, I managed to pull out my heater core without cracking the A/C. When *all* the fasteners were removed, there was just enough play to slide it out. Pointless, as it turns out, since my A/C was empty.
Wondering if the newer Gates PowerGrip SB clamps could be placed over the OEM connections for extra insurance?? Haven't used them myself but they work like heat shrink tubing. FWIW.

I have everything out just like in the pics. How in the hell do you remove the heater core and unit as one?
this has turned into a pain in the butt. Now I want to replace a bunch of stuff, deck, steam clean, etc. one day job will now be 2-3 day job.
