As it's plumbed up now, the vent hose runs down to a tee fitting in the heater bypass (just a short piece of hose to bypass the heater core loop). I still don't understand what exactly the steam vents do on these engines...

Well, actually, they do exactly what your asking

The steam vents are the water lines that are the highest point on the engine. Newer style engines only have the 2 pipes on the front of the engine, older ones like mine have 2 in the rear connecting to the 2 in the front. The hot water running through the engine will push any air out through those steam vents effectively keeping the cooling system free of air and healthy.

My steam vent is plummed straight to the radiator, but here are many ways of doing this. I think your fine putting it into the bypass as long as its working
