It is? I'll echo that statement about Toyota red, my two vehicles have pristine cooling internals even after all these years and miles. Ditto for my BMW on OEM blue and my Honda on Type 2. Seriously, it couldn't be any cleaner. There's nothing - no corrosion, no sediment, no goop. Where's the problem coming from? Aluminum head, aluminum block, aluminum radiator, aluminum heater core. Where is the galvanic potential coming from?
And those zinc anodes will not help. Like was already mentioned it's worse than doing nothing in accordance with that chart.

its a huge problem with todays cars. much bigger problem than in the past.i have tried many different things to stop galvanic corrosion and nothing works once it starts.
