Abstract
An engine thermal management system and method for a vehicle engine that allows for reduced coolant flow and energy consumption by the system, while avoiding excessive critical metal temperatures in the engine. The engine includes a coolant inlet in a head and a coolant outlet in a block. A variable speed pump pushes the coolant into the head inlet. A multi-port valve receives the coolant exiting the engine block and selectively routes it to various system components. The speed of the pump and the valve are electronically controlled by a control module, based upon various engine and vehicle operating conditions.
