I checked the freeze point of the coolant in my car and it was 0 degrees so I figured I'd change it. I drained the radiator and the block but only got about 5 1/2 or 6 liters out of it. I'm not sure what the total capacity is for these vehicles. I read that it was 8 liters but I have also found it listed as 7 liters. I didn't pull the heater core hoses and flush that out so I know some would be left in there. If I only left 1 liter in there I'm fine. I used Zerex HOAT coolant and it appeared that the car was full of Volvo coolant so the two should be compatible.
