A vehicular cooling system coolant-return manifold is provided that includes a plurality of ports reconfigurable by the user to open, such that coolant will flow into the manifold, or close, such that coolant will not flow into the manifold. The ports are opened and closed by rotating a valve spool in relation to the manifold body. The ports of the manifold are brought into alignment with holes in the valve spool to open a port such that coolant flows into the manifold. A plurality of positions of the valve spool in relation to the manifold body allow a user to select a position wherein the desired combination of ports are on and off.
