Coolant question

Hello everybody and good morning, if you're reading this in the early hours, I drive a 2008 Chevy Impala with the 3.6 L V6 and I was wondering when I should do a coolant flush. I'm currently at 153,000, mi. I'm not sure if it's even been done since before I got the car, but I heard that it is needed at some point during ownership of a vehicle, especially older cars like this. Thank you for your input.
