ABSTRACT:
This disclosure relates to a coolant system for an internal combustion engine including a turbocharger and an aftercooler. The coolant system comprises an engine loop and an aftercooler loop both loops utilizing a single pump. The engine loop includes the pump, the engine block and head, a first radiator, and a radiator bypass branch. The aftercooler loop includes the pump, the aftercooler, a second radiator, and a radiator bypass branch. Each loop further includes a temperature responsive flow control thermostat for regulating the coolant flow through the associated radiator and/or bypass branch. The thermostat in the aftercooler loop is mounted in the coolant intake line leading to the aftercooler, but it responds to the temperature of the coolant leaving the aftercooler.
