1999 Sierra Broken Heater Core Inlet/outlet

[Sierra54]

One of the hoses snapped off the inlet or outlet of the heater core attachments at the firewall. The hose on the driver's side broke off with the remainder of the heater core attachment still inside the hose.

 

Do I need to replace the heater core or is there another fix for this. Also, any ideas on a repair bill. I have a Chilton and have done some repairs myself but replacing a heater core may be beyond me.

I found this link to an older post with a similar issue but I can't access the link to the part they are talking about. I think it may be a heater hose connector Dorman part #800409. I have fuel line release fittings, will these work to release the old connector?

Thank you for any assistance.

Those are quick disconnect fittings. Remove them and install new ones or connect hoses directly to the HC pipes, then use hose clamps
