Default 61 heater core and valve

I am new to owning a 61 TBird. I love it,and get many thumbs-up when I drive through town.

Lately I am noticing antifreeze leakage in the front passenger compartment. I am told that this is a heater core and/or valve problem. I have the service manual, and it makes it sound pretty simple to replace. I am barely mechanically inclined, but feel confident that I can do the job. Any suggestions? My TBird doesn't have A/C. Or should I just connect the two hoses and use the car in the summer?

What parts should I order? It seems like I'll need the core, valve, and gasket. Anything else?

The manual doesn't have a diagram. Is there a schematic diagram of this job somewhere online?

Or am I opening up a can of worms and anti-freeze?

Thank you for any help you can offer.

Welcome to Squarebirds, Joe. I cannot guarantee your core doesn't leak, BUT... seems to me that others here have had the same issue. They said the seal goes bad and installing a new seal remedies the leak.

I believe this seal comes in a kit offered by some of the Thunderbird vendors. We are sponsored by a few, so go to the technical section and search for this issue and a vendor who carries the kit. - Dave

Hi Joe!

You might click on Search in the black border above. Type in Heater leaks. I got a number of threads when I did that. Read through them and they might be of help to you. Bob's Bird House, Don at Bird Nest, and a number of other vendors might be able to help, if you need parts. Although Carl ~ partsetal has mainly Squarebird parts, he probably knows how to fix that problem on a '61 Tbird. Others have had that problem and fixed it. Bob at Bobs Bird House has lots of parts, as does Bird Nest. You will find their contact information in the Advertisements Forum below.
