You should be careful at choosing liquids for Kia especially for vehicles having 3.5 motor. For filling up the system you will use 11 liters of special Red coolant type. Before choosing fluid note that engine code G6DB and volume of 3.3 were installed to your car in 2008. Only exact type of antifreeze will suit Kia Sorento cooling system. Otherwise Sorento made in 2009 won’t serve you long enough.
Use your 2.4 engine longer in 2011 Sorento by keeping these rules. There is an important thing for D4HB engines of Kia’s production – they expect good service. There is a big plus in servicing 2009 Kia Sorento with all regulations. Better buy 8.6-9 liters of good antifreeze in Red color.
