We cover three Impala generations. The 2000 to 2005 car uses 3.4- and 3.8-liter V6 engines, with a supercharged SS. The 2006 to 2016 car offers 3.5- and 3.9-liter V6 engines and a 5.3-liter V8. The 2014 to 2020 car uses a 2.5-liter four or a 3.6-liter V6.


Your 2012 Chevrolet Impala is from the ninth-generation Impala, which covers model years 2006–2013. 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 2012 model year.
Check the model year on your VIN: on a 2012 vehicle the 10th character of the 17-digit VIN is “C”. 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 14 years old, a 2012 vehicle often needs work on the cooling system, timing components, suspension bushings, motor mounts and corroded electrical connectors, all jobs where the exact factory procedure and torque values save time.
Same generation: 2006 Chevrolet Impala, 2007 Chevrolet Impala, 2008 Chevrolet Impala, 2009 Chevrolet Impala, 2010 Chevrolet Impala, 2011 Chevrolet Impala, 2013 Chevrolet Impala.
