Rust and corrosion in the coolant or just a broken part. I would reccomend having it replaced every couple of years, just to be cautious.

When a thermostat fails outright one of two things happen. The better thing is when the thermostat gets stuck open. The worst thing is when the thermostat gets stuck closed, and corks up hot coolant in the engine. Coolant trapped inside a running engine quickly overheats

contrary to what others think that the engine thermostat is a wax bead, its actually purely made of metal. The thermostat has special metal plate cover that is made of 2 layers of different kind of metal. Metal expands when heated, but some metals expand faster than others. One side of the plate expands faster. This makes the plate warp or fold. When the metal plate warps or fold the thermostat opens and lets hot coolant circulate.
Of course, the thermostat continuously opens and closes. All that expanding and cooling wears out the metal and eventually they layers start to seperate and they wont fold or warp anymore.
Time for you to get a new one.

Thermostats operate on the expansion and contraction properties of certain metals ar certain temps. There is a constant twisting and movement of the spring/metal in a thermostat. Twist something enough and it will either change form, break or both.
This is what causes a thermostat to fail. Actually, it's not if a thermostat will fail...it's when.

Thermostats almost never stick closed. They just get blamed for it all the time because they're the part everybody knows. They're made so they stick open when the spring gets weak, so you won't overheat. About the only thing that makes them stick closed is people putting them in upside down.

a thermostat is a wax bead that when exposed to water at the same temperature as its melting point will liquefy and allow water to pass through. When the water cools, the wax will harden and stop it opening. However, if the t-stat wax bead is badly overheated, it may change in composition, much like cooking an egg.

Thermostats are a maintainance item, they just go bad after time.

The thermostat needs replacement. It is broken.

It has come to the end of its story. Give it a decent funeral.
