I read a thread on here recently with two owners ditching their coolant because it was brown, so they replaced it. The joke is they replaced the nice modern OAT coolant the car came with (brown/orange) with crappy knackered after two years regular blue glycol...

There is a lot more variation in engine coolant than you'd expect. For the avoidance of doubt and for the cost of a couple of quid I'd be inclined to buy the genuine Volvo coolant from FRF rather than listening to internet wise men. As others have mentioned coolant changes are frequently ignored. You can backflush the system with fresh water after draining the old coolant, and then refill with the proper Volvo coolant for your model.
