It’s better to choose fluid in combination of 2009 year, 2.4 volume of motor and engine code of D5244T14. For filling up the system you will use 8.9 liters of special Green coolant type. Make sure you service system at Volvo with installed 2.4 engine correctly.
There is a big plus in servicing 2008 Volvo XC60 with all regulations. To endure car life take only Green antifreeze and pour not more or less than 11 liters. It’s obvious that every D5204T2 motor needs good service as stated by Volvo in instruction. Produced in 2013 the 2.4 engine in XC60 model will serve longer by this.
