Its seems like the main purpose of it is to reduce corrosion, increase coolant life, and reduce system pressure. But I don't think its meant to resolve overheating issues? Just because it doesn't boil until 375* doesn't mean you want to run the engine any higher than 210 still. And its not like we are trying to get 30 years of service life out of our coolant systems in our buggy.
If you're just wanting it because your coolant boils over when you overheat wouldn't you want to resolve your overheating issue instead of just running the engine until it melts down?
What am I missing?
