The maintenance manual notes to replace the coolant at 150,000/15 years. Seems quite a long time to replace coolant, wondering what others think? I have come across suggestions on replacing it every 3 years so I'm wondering what's the ideal schedule. Thanks!

I honestly would keep an eye on the color of the coolant. If it's still the same pink color then I wouldn't touch it until the recommended interval.

This really depends on your local climate. I live in a mild-cold climate and will do a coolant change every 24 months.

There is no problem with changing it early. Be sure to use the right coolant or have the dealer or indy do the job.
