Don't worry. The part you are referring to can be replaced. As far as the heater core, chances are it was bypassed because there was a problem with the core leaking into the vehicle. I attached a picture of the routing of water lines. Do me favor. If you can upload a picture of where it is leaking, it would help me. Also, is the rusted component leaking through a rusted area or from a connection?
As far as the heater core, are there two hoses running to the firewall of the vehicle?
