Leave it out for summer!

 

Not good practice....I have read somewhere and abrieviated here....

 

The thermostat is part of the cooling system. It is a door and a flow restrictor, the restriction (when the door is open) increases the back pressure of the coolant caused by the water pump within the block. The back pressure increases the boiling point of the coolant and keeps it "pressed" against the hot water jackets instead of it boiling away from them which would reduce the cooling effect.

 

A block / head can apparently see as much as 30 psi where as a radiator cap might have an 8psi spring in it.
