  • Failsafe thermostat for water-cooled engines
    Patent number: 4981260
    Abstract: A thermostat adapted for use in a cooling system of an engine designed to operate between minimum and maximum operating temperatures is partially constructed from a meltable material that has a controlled melting point at the maximum operating temperature of the engine. If the thermostat fails to allow coolant to flow from the engine to a radiator, thereby causing the temperature of the engine to rise beyond its maximum operating temperature, the meltable portions of the thermostat are melted by the coolant, resulting in a path for the coolant to flow from the engine and to the radiator.
