In order to actually do something, you need a potential difference - i.e. voltage so you can get flux - but when everything is connected to everything else, the potential is the same all over.

So what could it do ?

One thing it could have done is sort a grounding issue somewhere ...
The radiator is generally electrically neutral, being attached only by/through rubber grommets and holds. The engine is generally tied as a ground point, and the coolant flows through the block, which would essentially make the radiator a ground through a liquid conductor.
