It sounds to me like your coolant is old if it has no colour to it as such. My car has a green/blue coolant in the reservoir, but a Volvo specialist changed mine for me. If you're doing it yourself, nip to a dealership & buy genuine Volvo coolant. Its made for the car & then you have no issue of mixing an aftermarket brand with what's already in it.
Thanks Kev. I tested the coolant with one of those little things that has 3 floating balls in it. When I filled it all 3 balls went to the top of the tube then 1 started sinking slowly back to the bottom. This may be a stupid question ... does coolant have a potential impact on the car's heater???
