Well, you need some tools: torx head screwdrivers (you may have the right size in your trunk tool-kit) and a set of regular metric sockets. The job isn't terribly complicated, but it's sort of very awkward to do. The heater core is under the center of your dash top, but it is accessed from inside the aquarium. The aquarium is that area that's hidden beneath the black plastic piece that extends from your
windshield wipers to underneath the hood - the one with the washer
fluid line going through it. This is very easy to open, once the 7 or 8 torx head screws are removed. Now, if you look on the passengers' side, you'll see a long cylindrical shaped black plastic housing - that's
the AC evaporator and heater blower motor housing. The blower motor is at the end that's located in the middle of the vehicle. It is
this middle of the vehicle placement of the blower motor that makes the job awkward. One has to work in an area where one is always
bent and leaning over to do things. Anyway, that heater blower motor
has to be removed to get at the heater core, which sits directly behind it, which is in the cabin. That's why it's leaking onto your floor. The heater core is not far from the center vent and directly above the SRS module, which is accessed from a panel at the side of the carpet,
at the intersection of the floor and center console. Like others have noted, it could simply be a loose hose where it enters the core, or it could be the seal between the core and the plastic end-tanks, which is usually the case. I wouldn't be so concerned about the floor - it's very well painted/sealed. You should be concerned about damage to the SRS computer - Saab gets $1300 for those, although they can be found at salvage yards for a fraction of that.....again, as others have noted, Quasi has an excellent write-up on this...good luck!
