Can't seem to pinpoint engine coolant loss C70 1998

I saw a couple mentions of that over a matthews's volvo site. However, the coolant is being lost well aft of the engine itself. it seems like it's either coming out of firewall (somewhere other than the at the heater hose junction block) or it's being drained out through the cabin someplace. I can't see anything thanks to that aluminum heat shield. Just to be sure, the turbo's on the back end of the engine, right? Down low? This is my first turbo Volvo. However, on other models.. the turbo is usually on the exhaust side of the engine, up front...

I just took her over to the junkyard looking for a replacement hood release cable and some other bits. Before I left, I could see that coolant was *still* leaking out from under the car (same place) even though the engine had been shut off for a couple hours and the coolant expansion tank cap was off.

Aside from the twin pipe to the heater core, is there anyplace else inside the cabin where engine coolant would be circulating?

I really hate doing exploratory work w/o a sense of the source as I often break things when I get into a new part of the car for the first time.
