Abstract
A cooling system for an internal combustion engine includes a first circuit for cooling the cylinder head and a second circuit for cooling the engine block which are completely separated from each other and make use of a first fluid and a second fluid which are never mixed with each other. The flow of the first fluid circulating in the circuit for cooling the cylinder head is used, totally or partially, for cooling the second fluid which cools the engine block in a heat exchanger. Preferably, the second cooling fluid is the engine lubricating oil.
