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.


The 2001 Chevrolet Impala belongs to the eighth-generation Impala, built for model years 2000–2005. 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 2001 model year.
Check the model year on your VIN: on a 2001 vehicle the 10th character of the 17-digit VIN is “1”. 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 25 years old, a 2001 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: 2000 Chevrolet Impala, 2002 Chevrolet Impala, 2003 Chevrolet Impala, 2004 Chevrolet Impala, 2005 Chevrolet Impala.
