Default How often to replace green coolant

How often should I be flushing the green coolant from my radiator? I've heard 2 years/12,000 miles, 2 years/15,000 miles, and 2 years/30,000 miles.

In the past, ever since I flushed out my Dex, I've done fluid changes with needed service (radiator crack, tensioner swap, cam install, etc.). But I'm coming up on 15,000 miles without springing a leak, so I thought I'd check.

According to our 1997 owners manual, it says every 150,000miles or 60 months. That seems a bit long considering how much gunk and crap that can build up in that amount of time. Hope this helps.
