Abstract
A water pump assembly for controlling the flow of temperature control fluid in an internal combustion engine. The water pump assembly includes a housing with an inlet, an outlet and an electric motor assembly for causing fluid to flow from the inlet to the outlet. A housing is mounted to the inlet of the water pump and an outlet of a radiator. A valve member is located within the housing and reciprocatable between a first and second position. The valve member permits fluid flow from the radiator to the inlet in the first position and inhibits fluid flow in the second position. The valve member is positioned within the inlet of the water pump. A bypass inlet is formed in the inlet and channels a flow of fluid into the inlet. An electronic control system controls the actuation of the valve between the first and second position.
