The Gates K061166 serpentine belt for the 2019-2026 Chevrolet Silverado 4500 HD 6.6L and other vehicles drives the alternator, air conditioning and fan.
Squealing, cracks across the ribs or a glazed rib face can mean the serpentine belt is worn, though a weak tensioner or a worn pulley can be behind them too, so find the cause first. The V8-6.6L takes one belt for this drive.
This serpentine belt is also a direct-fit replacement for the 2019-2026 Chevrolet Silverado 5500 HD 6.6L and the 2019-2026 Chevrolet Silverado 6500 HD 6.6L. Driving a different truck? Open the "Vehicles it fits" section to check your exact model and engine.
