What is this?????
the intercooler or radiator? or something else?
look close and you'll see a wire standing there, broken and disconnected.
the wire is there because i put it there, it looks like it used to connect to that fitting but idk.
the wire disappears into the grease and grime behind the engine fan of the cummins 5.9.
i assume i hook it back up, but id'sure like to know what it is first.
thanks for any help
