    The below pictures from an endoscope show the condition of one of my aftercoolers after 2 seasons.  After having a look, do the think they should be serviced.  Thanks……

    Based on the fins-NO 

    No clue on the surfaces inside where the caps seal against the housing where all the nasty corrosion/pitting can take place If you park in fresh water or fresh water flush,  then you would be good as long as you follow my protocol for assembly
