Shelf life?
Matthew - Thanks for sharing! What was the shelf life of the kit you bought? I am tempted to order one, but if the shelf life of the strips is only 6-12 months then I would basically be paying $65 for one test.

I thought it was cavitation issues. The vibration makes tiny bubbles that implode against the cooling walls slowly eating away the liner.
I'm shocked Ford still isn't using a better coolant.
There are coolants out there that last MUCH longer.

Plus certain coolants, once they start to break down, become very acidic and/or corrosive.
Be very careful about switching to high-mileage coolant. Older diesels didn't have the emissions systems like today, so you could basically switch to just about any coolant (provided it was properly flushed) and drive as long as you wanted. With today's modern emissions, particularly the EGR which exposes coolant to excessively high heat, many high-mileage coolants don't hold up very well and actually can cause additional issues down the road.
Just FYI
