Have you checked if that statement applies to all vehicles? In my case, it's a 2019 D4, and there's no time or mileage interval specified anywhere. When the timing belt is changed, the fluid that spills when the pump is removed is replenished, but it's not completely drained. The reservoir holds 6.5 liters, but strangely, more than 4 liters are added. There must be a reason they don't change it. Until now, this might have seemed like common sense, but it appears something has changed.

You can measure the freeze point to give you some indication of it's condition. However coolant has many corrosion inhibitors and they dissolve when engine is used in time. It is good to change every 5 years at most.

That's what Volvo Cars told me on the phone today: that it's recommended to change it every 5 years.
