  • Patent number: 6508212
    Abstract: The present invention provides a cartridge thermostat system that permits removal and replacement of the thermostat without removing the housing or coolant manifold. In the cartridge thermostat system, a coolant manifold is mounted on a cylinder head of an engine. The cylinder head has an engine by-pass and a coolant port for receiving a pilot on the coolant manifold. The coolant manifold further comprises at least one thermostat port with an associated cartridge thermostat and at least one passage for appropriate coolant flow. The cartridge thermostat fastens to the thermostat port and operatively positions a plug to an engine by-pass and a sleeve to a coolant passage. A wax plug in the cartridge thermostat expands when the coolant is hot and thereby appropriately and simultaneously positions the plug relative to the engine by-pass and the sleeve relative to the coolant passage.
