2017 Nissan Altima 2.5 SV — need advice: Coolant is old by time but low mileage

Car only has 32k miles but the coolant is several years old. Would you change it based on age alone? I'm trying to prioritize maintenance that matters rather than replacing everything early. If I fix it I'll come back and update the thread.

This is usually cheaper to test than to guess. Write temp, speed, and in-gear vs coast when the 2017 Nissan Altima does it — then decide on parts. That's the branch I'd chase this week. Verbal 'we'll take care of it' is not a plan. I'm in no rush to be a hero on it.
