Nope. Heater core started to leak inside. Not all that bad getting the box out and the core removed. Getting it back in will be the fun part. It only leaked for about 20 seconds, so no damage to carpet, minimal gasket or firewall damage or evidence. Can't imagine it hurts to have one more perspective on the job, so I'll add my own simple version. The others helped. maybe this one will help someone else who reads here.
Short version of EX-tallation:
0. Look at the previous manual pages posted by MechEng, and look at the pictures, and read the section on removing the box. You won't "have to" do all it says, but it will help you doing this list.
0.1 remove glove box door and box and take many pictures front, and to the right and left, for reference later.
0.2 remove kick panel
0.3 Pull back carpet - more space, less water damage.
1. Remove hoses from inside firewall and remove two nuts on the studs near them that hold the box to the firewall.
2. Remove hose from under heater box that goes though the lower firewall.
3. Remove vacuum hoses and actuator cables from the small motor mounted on the box next to the bottom of the dash
4. remove that small motor (2 screws) push it out of the way of the box.
5. Pry off the several clips. There is one on the left and one in the back that you may not or won't see, but you will know they are there. (I didn't tell you, like the manual does) to remove the bolt that holds the top of the box to the dash with a short metal strap because I did, and in order to do it this way, I put the screw back in place to hold the top of the box and A/C core up and out of the way.)
6. Pull the box slightly out from the firewall - since you didn't remove the AC hoses in the firewall, you'll only be able to pull it in an inch or two...it's just enough.
7. If you pull the after market radio out, (or remove the center lower dash panel if stock) you can remove the right one of the two bolts/screws holding the plastic blower tube in place to get just enough room to scootch the bottom of the box out. (not necessary to loosen the blower motor like the manual says, couldn't find the two screws the manual talks about with the box in place anyway.
8. If you have done these things, you will be able to carefully pry the bottom away from the top slightly, to insure you have all the clips out, and begin to scotch/pry/wedge/tilt/wiggle/pull/push/do not yank, do not pull hard but maybe firmly, and voila, the bottom of the box comes out with the core in it, and leaves most of the rest in place.
9. Bottom of the box out of the car, remove the screws holding the doors/flaps in place, remove it, and then pull out the core.
From there, remove the foam gaskets slowly and carefully, pry lightly with a flat blade if necessary and don't tear them. I blew some air through the core underwater to see where it failed (unnecessary, but fun for my wife to watch me get a little soaked). My gaskets are in pretty good shape, but your mileage may vary...prepare to wait for new ones.
Depending on how long it takes and if there are any "tricks" to getting it back together, I may add an installation task list. Don't count on it.
