Dayco 5061380 serpentine belt for the 2007-2009 Chevrolet Silverado 2500 HD V8 6.6L and other vehicles is the main drive belt for the fan, alternator and power steering.
Cracks or fraying on the ribs, a glazed belt surface, or a chirp or squeal in normal driving can mean the belt is worn. Before you replace the belt, rule out a weak tensioner, a rough or misaligned pulley, and oil or coolant on the belt, since each of those can also make a belt noisy.
This serpentine belt also fits the 2007-2009 Chevrolet Silverado 3500 HD V8 6.6L and the 2007-2009 GMC Sierra 2500 HD V8 6.6L, with one belt per vehicle. If your truck is not named here, open the "Vehicles it fits" section to check your exact model and engine.
