6.7L Power Stroke – EGR Powertrain Secondary Coolant Flow


The second part of the EGR cooler is cooled by the powertrain secondary cooling system.
An internal air-to-coolant heat exchanger absorbs heat from the exhaust gases and dissipates heat to the atmosphere through the powertrain secondary radiators.
