I've heard that this stuff really needes to be flushed as much as the green stuff.
The green stuff has silicates and borates which do not cause problems unless they drop out of suspension in the coolant.Which usually means it's been overextended.
My boss's daughter has a 2000 Echo that had a water pump failure at around 65K with the original factory fill of the red stuff.
I have a Toyota that came with the red stuff but I flushed it out and put in the green about 2 1/2 years after I bought it(31K miles).No problems what so ever with the green stuff.
Planning to change it out before the end of this summer.
