Cold-start squeal in winter often prompts fleets to schedule seasonal belt service, and the Mack Serpentine Belt puts a fresh drive surface on the accessory pulleys in its circuit. Grip matters most on frosty mornings, when accessory loads hit a stiff belt all at once. Putting the Mack 20870833 on during that service lets the technician check tensioner and pulley condition at the same time. Drivers start the season with a quiet belt and one less thing to worry about at the first freeze.
