I have a bad heater core . should be easy to remove but how do I get the plenum off to access the core ?

Do you have the factory installed heater, or the dealer installed heater?
I think mine is factory, just a few small sheet metal type screws. I need a core also, the PO put in one with no temp control :005:, another thing on the list :002:
I too bought a car with no controls on the heater. In addition, there was no valve on my core. You may have this on yours.
The equipment to make it work like it came from the factory would be expensive. I ended up buying an inline valve that could be controlled by a cable attached to the dash control unit. The cable was about $10 and the inline valve was about $25 on eBay.
It works great. You can control the air flow and water flow from the dash and I'm the only person that knows it is a poor man's solution. I used it last winter in Denver and there was no problem.
I can send pictures if you want to see what I did.

I have all the dash cables but not a core with the valve. Good idea, I could use an inline one, I know what they are, but not sure if the stock cable will reach that far.. Right now I just have a manual shut off valve on the manifold, off in the summer, on in the winter :003:
Rich, it looks like factory but then I don't know what a dealer installed would look like

Ken..the easiest way to tell is looking at your firewall from the engine compartment side. There are two large openings on the passenger side..one above the seam in the cowl area, and a larger one right below it, below the firewall seam line.
The dealer installed heater will only be using the lower opening, and there will be just a cover plate on the top opening. The Factory installed heaters used both openings, as the units drew ouside air from the cowl.
I hate to appear ignorant about the heater , but is the core removed from the engine side
or the passenger compartment ? Ken
Ken if you have a factory heater assembly (long looking thing under the dash with three lever control in the dash) the heater core will come out from inside. The heater hoses of course removed in the engine compartment. Remove the defroster control cable from the assembly inside the car. Remove six or seven screws that hold the assembly together (look out for the defroster vent coupling) and the core will now be exposed.
