Coolant acidity?

Radiator coolant should be replaced every two years and use distilled water when toping off, it does deteriorate with time and heat, radiators will calsify and plug, if you live near salt water the radiarors will corrode to the point that you can run your finger down a row and have nothing but flakes, all coolant hoses should be replaced from 4 to 6 years dependig on where you live and type of commuting, hoses tend to rot from inside out and pin holes appear where they flex as the engine moves or rocks on the motor mounts when toque is applied.

All I can say is that is way off the wall..

I don't see how the coolant on the INSIDE be affected by what is on the OUTSIDE, period.

Coolant system is a closed system, granted there is a very slight chance of "venting" via the pressure cap, the chances of enough salt laden moisture from the outside accumulating enough to affect the INSIDE are pretty low..

In fact, don't tell my 2003 F250 that it's cooling system should be a pile of rotted rubber and the aluminum radiator and block should not even exist because it STILL has the ORIGINAL COOLANT INSIDE..

Yep, 14 year coolant with 200,000 miles with original rubber hoses. I have only needed to top off with a few ounces of coolant once when a factory clamp on the bottom radiator hose gave up from road salt..

And by the way, you think salt water spray from the coast is bad, come on over to the rust belt.. Yep, PA road salt in the winter is just as bad as living on the coast or worse (might be the same if you drove your vehicle into the ocean every day)..

Been fighting the battle of rust on the transmission lines and brake lines.. Cooling system, not so much other than the factory clamps rotting from road salt.
