It clips on up top iirc. You should be able to wiggle it off.

Have you removed the fasteners at the flange where the aluminum tubes meet the matrix?

If you don't separate the two you'll distort the tubes, which do not tolerate bending forces..

Yeah at that point I did undo the fasteners. Everything is out now.

The duct has to be pulled up, but it makes a bone-jarring sounds that plastic makes before it snaps. Sounds bad, but nothing broke...

and then what else happened? So did you get it out and replaced?

Yep, new h-core, water valve, o-rings etc. I'd be driving right now if I hadn't run a little short on coolant, gotta buy some more.

Yep. You can also replace the rubber gasket thingie on the firewall, and the two aluminum tubes (I didn't... but I'm on a budget and wasn't even going to replace the h-core but I figured that if the other stuff leaked at 178k kms, then I might as well do it too - for the health of the car :)). Also, make sure you retain all of your screws and square nuts as you won't get any new hardware with your parts. It's not a fun job, but doesn't really require a lot of skill.
