One last issue. The Dorman quick disconnect attachment I bought for the heater hose to core connection isn't correct. Doesn't look like my Tahoe actually utilized the quick disconnects (that's what I get for not checking). Do you know the part number for the white plastic connector? I've attached photos showing a comparison. Black is the Dorman connector.

Hope you got the Delco or GM ones. The Dorman ones are specifically known to not last very long and you might be doing it again very soon.
