Abstract
An engine cooling system is provided with an internal combustion engine defining a head cooling jacket and a block cooling jacket in a split flow configuration. A first thermostat is positioned at an outlet of the block cooling jacket and configured to control coolant flow therethrough. A second thermostat is positioned to receive coolant flow from the first thermostat and the head cooling jacket. The first and second thermostats are in a thermostat assembly within a housing. In response to coolant temperature being below a first threshold, a first and a second thermostat downstream of the engine in a thermostat assembly are closed such that coolant flows through a head jacket and the thermostat assembly to a pump, and such that coolant in the head jacket entrains a trickle flow of coolant from a block jacket through an interbore cooling passage, thereby cooling an interbore region.
