This could be related to the vacuum-operated heater control valve in the firewall area.

With engine off there is no vacuum and the HC valve closes.

With engine running and any amount of heat called for by the selector, the HC valve opens, allowing and a hose leak between the HC valve and the core to piss coolant.
