I recently replaced a leaking heater core on my 1999 Ford F150 (4.6L). Now I cannot figure out how to re-connect the "quick connectors" Dorman part # 800-403
I've tried to re-connect with the center locking clip and gaskets attached to the new heater core. (I also tried it with some WD40)
I've tried to reconnect it with the gaskets and locking clip attached to the black clip at the end of each hose.
I have the disconnect 5/8 tool and even tried to reconnect with that although I cannot get it to snap in? What am I missing
All I seem to be doing is pushing the new heater core and bending the 2 In/Out pipes.
