Abstract
A closure member for a urea tank used to provide urea to an exhaust treatment system of a vehicle comprises a closure member body defining respective urea inlet and outlet passages and coolant inlet and outlet passages therethrough. A valve carried by the closure member body, and a portion of the valve can be an integral one piece part of the closure member body, selectively blocks the flow coolant through the interior of the urea tank. When coolant flows into the tank, it is separated from urea in the tank by a recirculating conduit which returns the coolant from the coolant inlet passage to the coolant outlet passage. Coolant circulating within the tank heats urea therein. The coolant flow valve can comprise a solenoid controlled valve with an electrical connector carried by the coolant tank for making connections to wiring that provides power to the solenoid to control the valve. The closure member can also carry a support, such as a downtube, that can contain temperature and level sensing components with the closure member supporting a connector coupled to wiring for such components.
