Abstract
A cooling system has an air-to-air or first heat exchanger and a fluid or second heat exchanger mounted remotely from a main radiator for cooling an internal combustion engine. A filter filters a recipient fluid, such as an ambient air, before the recipient fluid passes through the first heat exchanger and the second heat exchanger. A cooled fluid is conducted to a flow of intake air for the internal combustion engine. A fan causes the recipient fluid to pass through the filter and the first heat exchanger and the second heat exchanger. The spent recipient fluid is discharged to atmosphere.
