Abstract:
A cartridge thermostat system for use in an internal combustion engine, the cartridge thermostat system comprising:a cylinder head comprising an engine by-pass, the cylinder head further comprising a coolant port; a coolant manifold operatively attached to the cylinder head, the coolant manifold comprising a radiator passage, a pilot cooperatively attached to the coolant port to thereby form a connection between the coolant manifold and cylinder head, and a thermostat port able to accept the cartridge thermostat; and a cartridge thermostat mounted in the coolant manifold to operatively position a plug adjacent to an engine by-pass and a sleeve to block a radiator passage whereby the plug is positioned against the engine by-pass and the sleeve is simultaneously positioned adjacent to the radiator passage by the cartridge thermostat when coolant temperature reaches a predetermined value.
