Radiator cap

[JOHN CT]

I'm trying to remove the thermometer form a quail radiator cap. I removed the 9/16 brass nut and I can't remove the thermometer. Does it pull out or unscrew? I don't want to break the glass. At times I feel like a bull in a china cabinet.
Thanks

Look at Snyders site to see the replacement for your cap. I clearly shows it is screwed in. Sorry I couldn't put the picture up but I tried to copy and paste and it didn't work.

I just tried to unscrew the thermometer and it will not move cw or ccw. So I'm going to let it soak in penetrating oil overnight.
Any other ideas?

I think there is some sort of sealer around the thermometer. If the quail hasn't fallen off like mine did, you may not be able to see it.

Yep, just did a search:

"To replace the thermometer, you have to remove the metal plug at the bottom of the Motometer probe (the portion that extends down into the radiator neck)--it's just crimped in place, and then "dig out" the grout that surrounds and secures the glass thermometer--use old dental scrapers for this, they work just fine.

I just want to give a update on what's going on with my quail lthermometer. I still can't remove it! I soaked it in penetrating oil for 2 days .I tried to turn it twisted tap it and bang it. Updraught found a article about plug on the bottom. There's no plug on the bottom of mine the only thing on the bottom is a 9/16 brass nut which I removed. Anyone else have, a better idea? There has to be a way. I just can't figure it out l guess I'm just having a moment

I was able to turn my thermometer in the quail by removing the brass nut and then gently turn the brass base of the thermometer with a pair of pliers. I wrapped the brass base with a soft cloth first. Be gentle!
