Looks like aluminum wasn´t to happy about something...
If everything else is iron on the engine...i would clean and go steel tubing.
Even if the water has some impurities anti freeze should be able to handle it.
Fast check is to measure freezing point...if it starts to change the additives in the antifreeze is used up and time to change.
