The corrosion inhibitors in the coolant become depleted with time. 2 years is prudent with normal stuff, and 5 years is likely good with long life coolant. I use Zerex Asian Engine coolant with a five year life.
Nobody knows why Suzuki has such short maintenance periods on many items. I know of no reports of any failure relating to extending some of the periods out to the usual intervals.
