That's what my engineer brain was telling me, even though a particular mechanic disagreed.

I hadn't thought about a soft plug or other way to plumb something like this in. I was looking a long while ago for an in/out set of plugs so I could plumb the coolant into my hot water tank loop to keep that warm underway, but never found one. I didn't look that hard, though, and I bet it could be in my Volvo manual.
