Threads of Heater Core Replacement

[Blkhwk]

I did a search but only found my post.
Does anyone know of threads dealing with the replacement of the Heater Core.

Oh yea, and my other problem, upper leak in the coolant system......

Do you need a copy of the removal from the manual?

Thank you so much for the offer. I have a service manual. It's helpful, but not like having someone from here that has had the issue and solved it.

The first problem I ran into was a leak in the system. Replaced the thermostat housing and the main hose from the "fill" (degas) bottle. Flushed the system and filled with coolant. That solved the "leak" and eliminated the "core" as a problem.
Voltage test at the valve "failed" so now I'm thinking it's the "sending unit". Fortunately I happen to have another TBird sitting around that works, so tomorrow, I'll switch "sending" units and try to "isolate" the problem. I'm "narrowing" things down.
Thanks to all of you that are wanting to help.
