Dog bolt easily came off with 1 1/8 socket on breaker bar and pipe wrench holding the hub. Perhaps a PO has replaced timing chain before???
The issue now is the steering arm bar is in the way of pulling the whole hub off with the pulley.
Should I push pulley back as the hub is worked out forward? Will that eventually clear or is there another approach?

You may find it is clogged in which case fiddling in there with a bamboo skewer, stiff wire or even a drill may loosen things up. As for where the water will come out if you put it into the heater hose connection - pretty much everywhere.

A leak significant to show as coolant loss and overheating would not necessary have any visible traces in the exhaust. One advantage of have antifreeze is that such a leak may be smelled more easily than it is seen.
