If the thermostat bulb element is "toast", there's no replacements. You have to find a "good" one and have it changed. I had to do this for the Cad.
For the most part they aren't made to take apart, but people have learned to.
The guy that repairs them is Tucker's,
www.heatercontrolvalve.com
and as far as I know he's the last. He and a son do this and Jim's up there in age - older than I. He uses the telephone. I sent two in to get one back.
Usually, if the seal is gone, they leak and don't shut off. There are some universal electric ones out there that can be used, but getting to fit is trial and error and 6V complicates life. Manual valve on a cable is another option. Some just by-pass. Everyone goes through this as a period owner/restorer if they want heat.
