Abstract
A liquid cooled internal combustion engine including a water heated plenum associated with the intake manifold and a temperature controlled plenum valve in the water line extending to or from the plenum and operable to control the flow of water. The temperature controlled plenum valve comprises a plastic body including a base wall and a peripheral wall and a plastic cap including a base wall and a peripheral wall surrounding the peripheral wall of the plastic body. The peripheral wall of the base has a radially outwardly extending annular rib and the peripheral wall of the cap has a radially inwardly extending rib. The ribs are adapted to pass over one another to provide a snap fit during assembly. The base wall of the body has integral O-ring retainer for retaining an O-ring. A bi-metallic disc is positioned in the body within the confines of the peripheral wall of the body and normally engages said O-ring and is operable to engage the O-ring when the water temperature exceeds a predetermined amount.
