There are two styles of thermostats they are both sleeved.
The bellows style is an old antique style of thermostat.
The problem with these is that when the pressure increases in the
cooling system it colapses the bellows and closes the thermostat.
This will cause the system to overheat. So if you are using a higher
presssure in your cooling system you will overheat with the bellows
style thermostat.
Also the bellows style if it is to fail it is in the closed position,
the wax capsule style thermostat is designed to fail in the open
position.
