Boil water. Drop thermo in it. If it opens in 10-30 seconds its good. If it doesnt its bad. Easy peasy.

If you need a new thermo, go buy it from NAPA. They sell pretty much OEM quality thermo, unlike the ones you get from autozone.

A good whack from a rubber mallet or your fist should do it. The sealant is probably holding it pretty tight if it hasnt been removed in a while.
