2012 GMC Sierra 1500 Serpentine Belts

Genuine GM serpentine belts for the 2012 GMC Sierra 1500, at wholesale prices. Belt length is determined by the accessory layout, which changes with AC, alternator rating and tow package. GMT900 through 2013, K2XX from 2014 to 2018, and the T1XX from 2019 with the CarbonPro bed option.

Symptoms to look for

Squeal on cold start, visible cracking, or a belt that keeps throwing. On a light duty pickup, single or dual rear wheels, gas or diesel, and cab configuration divide this group more than the model year does.

Ordering correctly

Materials and coatings are specified, not approximated, which is why factory parts last through more heat cycles. Check the VIN before ordering anything that has to bolt to something else. Shipping is calculated on real weight and distance, which usually beats a padded flat rate.
