A coolant flow control management system includes an integrated pump coolant flow control and heat exchange device for delivering engine coolant to and from the engine. According to the system, coolant flows from the engine and is delivered back to the engine after passing through various coolant branches while flow is regulated by a control valve part of said device, then passes through a heat exchanger part before being returned to the engine by a pump part. Systems of the invention are particularly useful with all-electric and hybrid vehicles.
