A thermally actuated fluid shuttle valve that is a three-way direction control valve that shifts when fluid passing through said valve reaches a preset temperature. The control valve, including three ports, an internal shiftable spool, and a thermal element, wherein fluid entering a first port from a source of heated fluid passes around a thermal element and out of a second port, until the fluid is warm enough to cause the thermal element to expand, thereby shifting said spool so that the first port is closed, and the second and third ports are in fluid communication with each other.
