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.



Your 2006 Mazda 6 is from the first-generation Mazda6 (GG), which covers model years 2003–2008. 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 2006 model year.
Check the model year on your VIN: on a 2006 vehicle the 10th character of the 17-digit VIN is “6”. 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 20 years old, a 2006 vehicle is in the age range where wiring, rubber hoses, seals and corrosion repairs take most of the work, and where original factory information is hardest to find.
Same generation: 2007 Mazda 6, 2008 Mazda 6.
All Mazda 6 model years: 2006 · 2007 · 2008 · 2009 · 2010 · 2011 · 2012 · 2013 · 2014 · 2015 · 2016 · 2017 · 2018 · 2019 · 2020 · 2021
