We cover the Mazda6 across three generations. Engines include 2.3- and 2.5-liter fours, 3.0- and 3.7-liter V6 units, the Mazdaspeed6 turbo, and from 2014 the 2.5-liter Skyactiv-G and the 2.5-liter turbo.



Model year 2019 is part of the third-generation Mazda6 (GJ/GL) (2014–2021). Most procedures are shared with the other years of this generation, but engines, options and wiring changed from year to year, so the manual is made for the 2019 model year.
Check the model year on your VIN: on a 2019 vehicle the 10th character of the 17-digit VIN is “K”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.
At about 7 years old, a 2019 vehicle is usually past its basic warranty. Typical jobs at this age are brakes, suspension parts, fluids, the 12V battery and diagnosing sensor faults with the factory wiring diagrams.
Same generation: 2014 Mazda 6, 2015 Mazda 6, 2016 Mazda 6, 2017 Mazda 6, 2018 Mazda 6, 2020 Mazda 6, 2021 Mazda 6.
