Great technical information there
WVZR-1......appreciate the detail.
I am assuming the Heater Hose Connection is something like this....
Does this mean you can "release" the heater hose from the connector?
I am thinking this Connector (with black insert) is actually the Heater coolant (hot coolant) to the Heater. The Connector with red cap (on thermostat housing) is Coolant Returning from Heater to the Thermostat Housing.

Have you or are your intentions to remove the complete housing to remove the remnants of your nipple that's broken off?

Large diameter pipe with red cap is cooled Coolant from radiator.
Small diameter pipe with red cap is cool coolant from Heater.
Small diameter Connector with black insert is Hot coolant going to Heater.
Large diameter pipe with no cap is coolant returning to Water Pump.
Medium diameter pipe to right with no cap is coolant return from Injector Housings (recirculated coolant) when end of thermostat is open by pressure (not temperature).
