I've attached two thumbnails - one for heater core inlet hose routing and the other for outlet return.

You are satisfied the heater core is not blocked. You know the inlet hose (lower) is warmed by coolant. I'd try loosening the heater outlet hose (upper) to verify coolant is under significant pressure (do before coolant is hot).

Lack of pressure could be due to bad water pump or blockage in pump outlet plumbing.

Significant pressure at heater outlet would indicate (to me) the heater return path is obstructed, either in the hose or in engine return plumbing.

I try to visit forum often but suggest you use private messages if in a rush (comes to cell) and include email address for extracts. I seldom check visitor messages so please don't use.

REWARD EXCELLENCE!
