Cleaning:
External Fins: Clean the fins carefully using low-pressure compressed air (directed opposite to the normal airflow) or a soft brush. For heavy grease and oil, use a dedicated aluminum-safe fin cleaner or degreaser, followed by a gentle water rinse.
Internal Core (Coolant Side): This is part of the engine's cooling system. When the engine coolant is changed and the system is flushed, the aftercooler's internal passages are also cleaned.
This 354-2831 aftercooler is used for C27 C32 engine.
