I've scraped all of the remnants of the old hardened seal (the one the thermostat seals against when it heats up and extends) out, but the replacement won't go in-it's a little too big and not flexible. I was about to try softening it up with a heat gun, but I just checked a few old threads here and apparently there's metal ring that also has to come out. I guess that would explain why the new seal won't fit. There's no metal ring with the new seal-it seems to be all plastic.If I pry the old ring out, does it have to be replaced? I didn't see any sign of one in the parts diagrams-maybe it's molded into the replacement seal?

the old seal is actually a metal ring that is wrapped in the rubber sealing material, simply get a screwdriver and hit the metal ring from the side this will bend it into the center of the hole remove it and then clean out the hole and insert the new seal

Here's one that still has the rubber on it and after it was bent with a screwdriver as Stan mentions. After you distort it enough you can grab it with some pliers.

I'll bet the new one has a metal ring inside it, too. Your old one was just trashed so you could see it.

I got it out without a problem-I didn't realize that the seal has the metal ring embedded in it. Thanks!

hehehe I just worked this one out after trying to fit the new seal for around an hour.
