2024 Tesla Model Y — coolant is old by age but mileage is low

GarageNomad373Community StarterAug 19, 20262024 Tesla Model Y Long RangeDenver
The vehicle has relatively few miles but the coolant is several years old. I am trying to prioritize maintenance by actual risk. Would you replace based on time alone? Mileage is about 18,000.

This is usually cheaper to test than to guess. Two 2024 Tesla Model Ys can feel identical and have different causes, so measure before you copy someone else's repair. You'll know quickly if you're on the wrong tree. This is from a 2024 Tesla Model Y in Denver. Stop there until you know. This is the version I'd tell a friend.

Tried a second charger / second scan and the story on the 2024 Tesla Model Y didn't change. I refuse to clear codes until someone else sees them.
