An engine cooling system comprises an integrated arrangement for pumping liquid coolant with a single pump through an engine and into heat exchange relation with various auxiliary heat loads in a combustion engine system. The coolant is further circulated by the pump from the engine and the various auxiliary heat loads to a single dissipation heat exchanger for dissipation of the absorbed heat energy. The cooling system is designed for maintenance of the engine and the auxiliary heat loads at individually selected operating temperature levels.

In a combustion engine system including a combustion engine, a charge air cooler heat exchanger, a refrigerant condenser, and an oil cooler, an engine cooling system, comprising: a circulating pump for circulating a liquid coolant into and through the engine; splitter means for splitting the liquid coolant exiting the engine into a primary flow constituting a substantial majority of the liquid coolant for recycle to said pump and a secondary flow constituting a substantial minority of the liquid coolant; a cooling heat exchanger coupled to said splitter means for passage of said secondary flow to reduce substantially the temperature level thereof; means for dividing said secondary flow exiting said cooling heat exchanger for flow in parallel through the charge air cooler heat exchanger and through in series the refrigerant condenser and the oil cooler; and means for recombining said divided secondary flow and for returning the same to said pump for mixture with said primary flow and recirculation into and through the engine. In a combustion engine system including a combustion engine, a charge air cooler heat exchanger, a refrigerant condenser, and an oil cooler, a method of cooling the combustion engine system comprising the steps of: circulating with a pump a liquid coolant into and through the engine; splitting the liquid coolant exiting the engine into a primary flow constituting a substantial majority of the liquid coolant for recycle to the pump and a secondary flow constituting a substantial minority of the liquid coolant; passing the secondary flow through a cooling heat exchanger to reduce substantially the temperature level thereof; dividing the secondary flow for passage in parallel through the charge air cooler heat exchanger and through in series the refrigerant condenser and the oil cooler; and recombining the divided secondary flow and returning the same to the pump for mixture with the primary flow and recirculation into and through the engine.
