It’s better to choose fluid in combination of 2010 year, 2.0 volume of motor and engine code of LFF7. In other way 2009 5 won’t be used quite long and efficiently. For Mazda 5 it’s important to have optimal antifreeze inside. It’s important to use 6.5 liters of coolant which has Red color. Make sure you service system at Mazda with installed 1.8 engine correctly.
Use your 2.0 engine longer in 2008 5 by keeping these rules. So better use Mazda’s advice for servicing 2010 5. If you choose other than Red coolant or use less than 6.5 liters, you can’t expect normal work. Every Mazda owner should remember that engines with code LF5H are quite demanding.
