Connection of Systems:
Charge Air Piping: Connect the charge air hose or piping from the turbocharger outlet to the aftercooler inlet, and from the aftercooler outlet to the engine intake manifold. Ensure all clamps are tight and secure to prevent boost pressure leaks.
Coolant Circuit (if applicable): The D398 typically uses an air-to-water aftercooler (heat exchanger). Connect the engine coolant hoses to the correct inlet and outlet ports on the aftercooler.
Bleeding Air: It is crucial to bleed any air from the coolant circuit after installation to prevent hotspots and ensure efficient heat transfer. Follow the engine's specific procedure for coolant system bleeding.
Drain Tubes: Ensure any condensate drain tubes are correctly routed and unobstructed.
This 365-1312 aftercooler is used for 773E truck.
