heater tube connection leak
Just fired up my 2001 Deville after headgasket/studding repair and noticed I have a coolant leak out of heater tube at crossover connection.
It is leaking out of connection point of item 1 and 2 in this diagram.
Anyone know what the method of sealing is here? Oring perhaps? Thanks.
BTW engine fired rite up and ran good

Re: heater tube connection leak
GM quick connect with nylon snap fingers and O-ring. Replacement fittings on the Help! racks at large parts stores. Your diagram is correct.
