The 2018 Colorado serpentine belt is responsible for transmitting rotational engine power to auxiliary systems like the AC compressor, alternator, and water pump. If the belt breaks, these crucial systems will not work and you will not be able to drive, so it's important to keep an eye out for signs of wear like abrasions, cracks, and damaged ribs.
