I think Jon is on to something. I have learned to listen when he speaks.
It's not that farfetched, I replaced Subaru head gaskets that are extremely prone to developing a coolant leak. Guess what! there is a ground strap from the head to the frame just where the gasket fails. So a small current is trying to move from the engine block through the head gasket to the ground strap on the head. All of that to say that a potential solution may be to make sure the top and bottom of the radiator are grounded to a common point on the frame.
If you have a good voltmeter it would be a just for grins exercise to measure any potential between that bottom rail in your picture and a ground lug over by the battery.
