Answers :

There is no replacing of the inlet outlets on a heater core. You will have to replace the heater core.
If its the nipple behind the alternator that goes into the manifold u will need to be extremely careful because the nipple gets corrodes and breaks off and the aluminum manifold has a tendency to break while trying to remove the threaded end with an easy out the part is only 20 bucks but to replace it is a nightmare good luck
