Abstract: A method of operating a cooling circuit of an internal combustion engine is disclosed. The engine is equipped with an engine head, and the cooling circuit includes a pump configured to deliver a variable flow of coolant through the cooling circuit. A coolant flow rate to be delivered by the pump is calculated as a function of an engine load, an engine speed and a desired engine head temperature, and the pump is operated to deliver the calculated coolant flow rate.
