The radiator is bolted to the car engine/frame/chassis, so it's on the "ground" side of things electrical.
The coolant, being mainly water + dissolved acids and bases, is conductive, so once again it's on the same electrical "ground" side
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.
