About

2018 GMC Sierra 1500 Belt

In order to transmit power from the engine to auxiliary systems like the alternator and water pump, the 2018 Sierra 1500 belt connects pulleys on each of these systems with one on the engine. That means that these systems will stop working if the belt breaks, which could leave you stranded. Abrasions and cracked or damaged ribs are sure signs of a belt that's on the way out. Check out our selection of 2018 GMC Sierra 1500 serpentine belts to find the right part at the right price.
