Apparently the heater core is leaking and thus disconnected in the vehicle I just acquired. As we are all in Canada, heat might be nice to extend the driving season into late fall before i store it... I understand many parts from the Biscayne fit the Strato Chief.
Anyone have any experience in a) part source and part number and b) how much of the dashboard I will have to remove to get to it :)
Id recommend a recore at a good local shop if you can find one. Reproductions of these can be questionable quality.
If like my 63, no dash removal needed. The process will be in those manuals when you get them, you remove the nuts from the studs on the firewall side. It takes a lot of patience, small hands, small sockets, to access those up by the passenger fender.

I just did my heater core in my 64 Parisienne Safari recently, and It's fairly simple - provided you don't have AC. If so, consult a manual.
There's 5 nuts on the firewall side. The lower left one is a little tricky to get at, but it's the hardest part of the job.
Inside behind the glove box, the heater box will pop out and lower down. There should be enough slack in the cables that you won't need to disconnect anything to get at the core.
NOTE: The box has a foam gasket that may fall apart when you remove it. I used a couple dabs of RTV silicone to hold it together while I reinstalled everything.
I picked up my heater core from the local Napa, but double-check the part numbers. The one I got wound up being 2" shorter in length and I had to shim it with some foam.
This is also a good time to lube the moving parts, so have a spray can of white lithium grease handy.
Good luck!

Hello ZIGZAG - thank you for the detailed photo series - looks straight forward enough and as you can see in the attached (filthy engine bay as I haven't got my hands on it yet) the heater core box you detail is indeed also in my Strato so your step by step is fantastic. Thanks as well to all the other experts who weighed in on sourcing and rebuilding solutions - Confident I can get this bit done reasonably easily - can't wait to see what else is one deck when it arrives - in about three days. Cheers to all

Antique Chevrolet in Ontario had the foam gasket when I did my heater.

Happy to help!
Looking at your photo, I see the lower hose was cut off. I'll bet the core is leaking because the lower hose was sized to the pipe, and all the prying to remove it caused a hairline crack where the pipe attaches to the core. I may have seen this before.
I've been journaling my tinkering on my 64 wagon at the link below, which has many similarities to your Strato Chief. Maybe you'll find something in there that is useful as you continue your work:

Your project report for the wagon is fantastic - amazing to see all the work you have done. Thanks for sharing the link and, the process you have gone through - very helpful.

Common rookie mistake. Not that I would know anything about that either...
Years ago I started using aa razor blade to slit the hose once the clamp is off. No more twisting the hose to remove it from the core. Replacing heater hoses with new hose is cheap vs. core repair or replacement.

Great advice- I absolutely would have made that mistake, but thanks to all, I'll bust out a razor for all hoses being replaced :) Thanks!
