How would my trucks thermostat get riped into two pieces?

I was driving the truck when it started to over heat. Just as I pulled into a parking lot to shut it down it the temp. dropped quickly. At this point I thought I would try and make it home. The truck never came back up to temp.

I thought maybe the thermostat stuck shut then stuck open. the next day when I change it...the thermostat was in two pieces. It actually looks as if it was ripped in two. Is it possible the pressure behind a shut thermostat could do this?How would my trucks thermostat get riped into two pieces?
pressure yes, also rust, age, and poor construction at the factoryHow would my trucks thermostat get riped into two pieces?
No. Thermostats undertake extreme temperature changes. From cold to hot and vise verse. Your thermostat just failed and came apart. Most car and truck PSI rating are around 16 psi. That is just pressure that is on both sides of the component.
parts break
i never heard of that happening before but the facts tell the story.must have been the combination of extreme pressure and a thermostat with a weak spot if it came apart.
