Oh my. This hose is bulging.

which one is this and how difficult to replace? I've looked through the diagrams and parts list but wanted to get some insight from the community.

Time to get a new one.
Your choice, stock or cut it in half to remove and take it to the store and get a replacement the same size, silicone would be my choice.

The hose is listed as:

Housing To Coolant Inlet Hose AJ811638 (supercharged)

As for difficulty, the closeness between these two metal hose fittings is about 1.5" (inner radius) and 3" (outer radius). I do not know if anyone has been sucessful in finagling the new hose back in by just undoing its clamps and disregarding this following suggestion:

I suggest undoing the aluminum outlet pipe /thermostat housing by removing 4 screws (2 into each cylinder head). Consequently, when separated, the (2) Water Outlet Seals C2C11477 (on the housing for each cylinder head) will probably be age/heat flattened or worse and need replacing.

Thermostat housing to coolant inlet. I changed mine a couple months ago. Helps if have clamp pliers. The lower opening was “welded” to the metal. Cut in half and slipped an awl between rubber and metal to release.
