About the 2014 GMC Sierra

Model year 2014 is part of the K2XX Sierra generation (2014–2018). It is the first model year of this generation: the platform, wiring and many procedures changed compared with the previous model, so a manual for an earlier year will not match it.

Check the model year on your VIN: on a 2014 vehicle the 10th character of the 17-digit VIN is “E”. 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 12 years old, a 2014 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: 2015 GMC Sierra, 2016 GMC Sierra, 2017 GMC Sierra, 2018 GMC Sierra.
