I can't find anything like this in the parts catalogue or the service manual. I've seen threads about a heater core bypass mod, so I am going to read those and see if maybe that's what someone did here.
After leaving this for a day, it definitely looks like my coolant leak is coming from one of the clamps, so I'm letting it drain out a little more before I start pulling stuff out.
