It seems to me that your cap should have let off the pressure in the system
long before this should have happened. Have you checked to see if the cap is
any good?

Have you had it flushed out too? Water pump and fan in good condition? Stock
fan, or aftermarket? Maybe switching to an electric fan would help if it's
overheating at low speeds. Thermostat tested, not just replaced? I've had
thermostats fail within a year or two of being installed.

If you're replacing it anyway, and are just going to trash the old one, maybe
a Sawzall could provide some additional clues. Or, do you have a local
radiator shop that can have a look at it?
