Do you need to change it? Dexcool (OEM) is rated for 5 years or 150K miles, or forever. At any rate, don't use green. Use only Dexcool, or a quality brand labeled "meets or exceeds Dexcool", not just a coolant that isn't green. Premix or 50/50 with full strength and distilled water.
It’s been 3 years and 61k miles....has orange in it now
