Unfortunately I'll be preoccupied by the mentioned heater hose and the rewiring of the ETA on my second car, looks like it would've been a great opportunity to meet Gerry and thank him in person for his power steering pump write-up that I made use of not long ago.
This will be the second time I replace the three-way hose (first time on this car) but the space to work in looks a lot smaller than I remember. I'd be willing to try doing a write-up w/pics for the benefit of those encountering the tell-tale mysterious coolant puddle for the first time.
