You should be careful at choosing liquids for BMW especially for vehicles having 4.4 motor. To maintain cooling system you need 13 liters of Green coolant. Before choosing fluid note that engine code N62B44A and volume of 4.4 were installed to your car in 2005. Only exact type of antifreeze will suit BMW X5 cooling system. In other way 2009 X5 won’t be used quite long and efficiently.
If you choose other than Green coolant or use less than 13 liters, you can’t expect normal work. Every BMW owner should remember that engines with code M57306D3 are quite demanding. There is a big plus in servicing 2005 BMW X5 with all regulations. 4.4 X5 motors of 2006 year will serve more by optimal service.
