Thanks for all the info I appreciate it. I will probably tackle the dash and core this fall.I just wanted some info on the heat issue. Did not know if mine is coming from the core or its the firewall/flooring where all the heat pours through. It's not been too bad but when it reached 100 in the northeast it was a hot one for just an hour ride.... Being a driver I'm sure the core is ready to let loose so I agree with the since everything is out dash off change the core. Just wanted to know how much was involved. As usual once yo have done one it goes  a whole lot better and faster. Again thanks for the info and will let yo know when that happens. For now just enjoying the summer after the tire blow out!!!!  It really runs nice and a nice ride with 4 new tires on her.  Just don't look at the right rear panel. OK Thanks again BB78

Babyblue - thanks for making this a current topic...I too will be doing the heater core dance this fall.  Brian - thanks for the photo documentary of the replacement - that will come in super handy.  Mine already peed in my car - fortunately most of it ended up on my floor mats, not the carpet.  So we have already preformed bypass surgery - transplant scheduled for this fall/winter.

Just removed my heater core and found a broken part.. imagine that... anyone know where I can buy one like it or I'll have to make something... don't trust glue ... and don't want to ever take it apart again 

 I t fits the flapper door that i believe directs air to the floor or Def.
 Not sure but  attached is a picture of the part



In this picture it is just behind the wire bundle attached to the door



Tnx,
Ray

Joe, I believe the valve is closed by the presence of vacuum and without vacuum it is open allowing water to flow.

The no-heat problem was not the control valve being stuck. Someone decided to loop the heater hoses in and out of the valve to bypass the heater core. This is what I found underneath:

Odds are very good that the reason they did that was because the heater core leaked. Mine is like that too because of leaking core. Winter project

Joe be really careful taking off the old hoses..try and cut them along the heater core pipes so you can take the old hoses off in pieces..don't try and twist them off..chances are it could crack the core solder joints or pipes if you do..don't ask me how I know. Rich
