My '66 has about 80K on it. The heater core has never been replaced and I'd like to keep it that way. I've replaced them before and wouldn't mind not doing another. Is there anything I can do to prolong its' life....frequent cooling changes, etc., or is it just a matter of age that causes it to fail?

Obviously, proper maintenence of the coolant is an element of prime importance. The use of a "HOAT" coolant formulation (like Zerex G-05) might be a little beneficial, although I think that most of the newer "all-metal" formulations will work just about as effectively.
Otherwise, it's just a matter of time. All you can really do is maintain the coolant well, NEVER-EVER stress the tubes (always slit, peel and remove heater hoses), and, otherwise, just let time take its natural toll.In Appreciation of John Hinckley- Top

If you need to remove the heater hoses from the core nipples (changing heater hoses, etc.), DON'T try to "pull" them off the end of the core nipple - you're likely to crack the solder joint between the nipple tube and the core tank. When removing a heater hose, slit the portion of the hose lengthwise that's on the tube and "peel" it off carefully so you don't stress the tube.- Top

Re: C2 heater core
Mine (on a 67) lasted only about 25 years and about 50K miles. Ruined the front carpets. I'll admit that it sat for a long time, and before I got into the restoration mode, I wasn't too fussy about maintenance. But the Vintage Air system took care of the problem and replaced the second heater core with the heater box.
