Is 30k mi. Coolant drain and fills overkill?

I do as well.

That's because they assume either you are flushing with tap water or not flushing at all and just draining and refilling which could leave 50% of the old coolant still in the engine. If you flush repeatedly with distilled water (4-5 times) so what drains out is pure water, I'd have no problem following the original recommended replacement interval. Spending an extra $10 for 10 gallons of distilled water is nothing over 100,000 miles.

What would happen if you added a coolant filter that is charged with the white chemical additives inside??

I see no harm in changing it early. I change mine in the Accord every 3 years. I am of the mindset that it is cheap insurance.

The vehicle made by GM so it will use GM coolant. See pages 294-297 of your 07 Vibe owners manual.

I remember traditional silicated Prestone was meant for every 15k up to one year. I went to a Japanese car specialist that insisted in using OEM spec fluids, but even for Honda/Nissan/Toyota they simply used regular yellow bottle Prestone and recommended changing it every year. I don't believe Prestone still makes it though. What they have now is a universal coolant they say is good for up to 5 years or 50k miles.

Is it silicates? I think I've seen this before and they're just selling it as a universal coolant.
