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 2015 Chevrolet Impala is from the tenth-generation Impala, which covers model years 2014–2020. 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 2015 model year.
Check the model year on your VIN: on a 2015 vehicle the 10th character of the 17-digit VIN is “F”. 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 11 years old, a 2015 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: 2014 Chevrolet Impala, 2016 Chevrolet Impala, 2017 Chevrolet Impala, 2018 Chevrolet Impala, 2019 Chevrolet Impala, 2020 Chevrolet Impala.
