Gates Super Duty Accessory Belt Idler Pulley

The Gates Super Duty Accessory Belt Idler Pulley line gives you replacement drive belt idler pulleys (also called accessory drive idler pulleys or serpentine belt idlers) for heavy-duty applications. An idler pulley guides the accessory drive belt along its path and keeps the belt routed correctly. This helps the belt drive components such as the alternator, water pump, power steering pump, and A/C compressor smoothly and reliably.

Key Features:

• Gates quality: Built to the standards of Gates, a long-established name in power transmission and belt drive systems.
• Durable bearings: Designed to hold up under high under-hood temperatures and demanding loads.
• Smooth operation: Helps cut belt noise and vibration and keeps the drive system running quietly.
• Contaminant resistance: Made to stand up to dirt, moisture, and road salt in harsh operating conditions.
• Helps protect the belt drive: A properly functioning idler reduces belt slip and uneven wear. This helps extend the life of the belt and nearby components.

Replace a worn idler pulley when you notice squeaking, grinding, or rumbling from the front of the engine, or when the belt wears unevenly. Replacing the idler together with the belt is common practice. Pick the specific part number below to match your application.
