With the recent discussion of radiator grounding, I've been giving the subject some thought and wonder how important it actually is. None of the modern vehicles i've worked on with aluminum rads and plastic tanks have any sort of electrical grounding, nor do any of the heater cores in most vehicles have electrical grounding. I do understand that grounding will help, but should it even be a concern? Are we obsessing over something relatively unimportant?
I would think that there is more risk of component damage from not replacing the coolant on a regular basis.

Are we talking about electrically grounding the radiator? Am I missing something?? The engine block is grounded and the radiator and the engine block have water flowing through them; water is conductive, so wouldn't that also ground the radiator?

Can someone explain why grounding of the rad is important, but not the heater core? They are both made of the same materials. I'm not disputing the theory, just wondering why we fuss over one component and not the other. Also wonder why it isn't a concern on the modern aluminum/plastic rads found in most vehicles today. None of them are grounded.

No it would not. In fact part of the problem is that there is water & glycol & additives running through the radiator. This can cause electrolytic (galvanic) corrosion between dissimilar metals which proper grounding takes care of.
