If the coolant doesn't have anti-corrosion additives (pH buffers, etc...) and it is a copper and aluminum system, it can happen quite a bit sooner than years. The worst case that I've seen (second hand) is a system with a copper block AND an aluminum block where the aluminum was anodized except for a pinhole spots. Those spots became pits in months.

He's right, though, in that if you use a proper amount of cheap anti-freeze you won't see any corrosion. You might lose a tenth of a degree Celsius or two, but the peace of mind is priceless.
